Backstrap Weaving – Ummmmmm……

Although I don’t typically wear four at once, I’m almost always wearing a wrist cuff when I’m traveling.
Wearing my woven work, such as these belts, is sometimes more effective at gatherings than wearing a name tag!

Wearing jewelry in the street here in Santa Cruz is not a good idea. I learned that the hard way in my first months here. Naturally, I do enjoy being able to do so when I’m away.

Backstrap Weaving- The Walls

The only time these got hung was at the ANWG conference back in 2015, I think. Terry (RIP), whom many of you may know as the owner of Magical Moons Etsy shop, made me some beautiful wooden hangers for them. I own and cherish several of her lovely swords.
Warp-faced double weave in the center flanked by a single-faced pattern of three-span floats.
For the panels on the left and right I used the ikat technique to create the bird shapes. The advantage of that over the center panel is that the background of the ikat panels can be a strong solid color rather than a pebbly one.
In these I also first used ikat to create the shapes which allowed the black areas to be solid.

Creating the shapes in ikat might seem like an excessive amount of trouble to go to just to get the solid rather than pebbly background but my long-term plan for this method is to create curved shapes that I otherwise wouldn’t be able to using the structure that I call Andean Pebble Weave. The block-shapes that I’ve created so far are just the warm-up!

GUATEMALAN SUPPLEMENTARY WEFT PATTERNING TUTORIAL.

I suggest you follow the beginner tutorial on supplementary-weft patterning here before attempting this second more advanced one. 

This tutorial was first presented over two weeks within blog posts so there are two parts. I have extracted the information from the two blog posts for this tutorial page. It shows the kind of supplementary-weft patterning that I learned in one particular town in Guatemala.

I wove a tree design at left using the various warp wrapping and inlay techniques that my Guatemalan teacher employs and this was fun as I hadn’t done any of this since 2008 immmediately after my return from my first visit there.

I learned these techniques with my teacher Martine and her daughter Carmen in Santa Catarina Palopo on the shores of Lake Atitlan. I met Martine in Panajachel where she sells textiles in the street market. She took me to her home and spent one morning setting up the loom and then her daughter took over weaving and teaching me for the next week or so. She was a good teacher. Each motif was repeated six or seven times across the cloth. Carmen would show me five times what to do and then would let me weave the last one or two motifs to practice what she had shown.

The weavers set up their looms with great care. Martine was obviously more skilled at doing this and Carmen only took over when everything was set to go. The warp is wound with two crosses. The second cross helps hold the shed rod in place.

In the first part of this tutorial you will see a series of step-by-step pictures showing how the warp is prepared for this kind of supplementary-weft patterning. A plain-weave ground cloth is woven onto which the supplementary-weft motifs are woven. Certain warp threads are raised in each shed under which the supplementary weft threads are passed.

As the same warp threads for the supplementary weft patterning  are raised every time, they can easily be picked and stored on pattern sticks so that the weaver does not have to continually pick them up by hand for every weft pass. There are two sets of these warp threads. One set is made up of certain threads from the shed-rod shed and the other of certain threads from the heddle shed.

In the above picture you can see four passes of yellow supplementary weft under the warp threads which form the two pattern sheds.. All the motifs that my teachers showed me were created by passing supplementary weft thread under the warps in these pattern sheds.

Two pattern sticks are used. One stick is inserted under the selected pattern warps in the shed-rod shed and another holds the selected pattern warps in the heddle shed.

I show the process of picking and inserting the pattern sticks first in step-by-step pictures and then in a video.

LEFT: This is the basic loom set-up with shed rod and string hedddles in place. RIGHT: An extra stick is placed in the second cross to hold the shed rod in position.

In order to create the patterns, two extra patterning sticks need to be inserted. These are stored up beyond the shed rod. One is stored on top of the warp and the other underneath.

LEFT: To set up the patterning sticks, the shed rod shed is opened and the first set of patterning warps are picked up. Pick one, drop two, pick one, drop two across the width of the warp.. NOTE: I am using doubled threads so what looks like two threads in the photos actually counts as one thread. The weavers use a pointed stick to do this. RIGHT: The pointed stick is inserted under all the picked warp threads and then pushed up toward the heddles. This will raise the picked up threads on the other side of the heddles. Another stick is then placed under these threads on the other side of the heddles. This is the first patterning stick.
The first patterning stick sits up beyond the shed rod until called into use.
LEFT: A colored piece of weft is placed under the warps in the first patterning shed. This serves as a reference to make picking up the warps for the second patterning shed easier. RIGHT: The heddle shed is opened and the warp threads in the second patterning shed are picked up. Between each warp in the first patterning shed, there are three warp threads in the heddle shed. You need to pick up the middle one of these three warps. You will pick one, drop two, pick one, drop two all the way across the warp. The pointed stick is inserted under all the picked up warps. The pattern stick for these warps will be stored UNDER the warp and a special maneuver is required in order to do this…see the next set of pictures. (This is also all shown in the video clip a little further on).
LEFT: The pointed stick is moved up toward the heddles which will raise the picked up warp threads on the other side of the heddles. RIGHT: A stick is placed under the raised threads on the other side of the heddles. Then both the stick and the shed rod are raised in order to create a new shed underneath the two. In the picture I have my hand within this shed and will replace it with the second patterning stick.
Here you can see the two patterning sticks in place up beyond the shed rod…one on top of the warp and another underneath.

Now the warp has been prepared with its two patterning sticks ready to create patterns with supplementary wefts.

Watch the process again in the following video. I am using very thick yarn and only a few warps in the video just to demonstrate the basic process. The video is in two parts.

The second part of the video shows how to use the pattern sticks to raise the warps and lay in weft for some basic patterning. This is also explained in the photos below. I am using thick warp and weft in the video just so everything is easy to see.

Two wefts are used to weave the above typical patterns of Santa Catarina Palopo: a red weft is passed through the two main sheds (shed rod shed and heddle shed) to weave the red warp-faced ground weave and the brightly colored supplementary weft thread are passed under or wrapped around the patterning warps to form the motifs.
Below are samples that I’ve woven since my return from Guatemala.
Motifs are usually started and ended with four rows of supplementary weft in the patterning sheds forming the yellow brick-like design shown above. The colored pattern weft (in this case yellow) is passed through the pattern shed and then the main weft (in this case light green) is passed through the main shed.
The two pattern sheds.
In this picture I have laid in the first pass of yellow supplementary weft and am in the process of passing the main weft. Four rows of yellow weft are usually woven before starting a new motif.

Here concludes Part One of this tutorial on Guatemalan single face supplementary-weft patterning. So far we have looked at how to pick the two patterning sheds and store them on sticks up beyond the shed rod, how to open the patterning sheds and how to weave the basic brick design which separates the motifs on a piece.

In Part Two,  I will show you how to create the outlines of shapes by wrapping the supplementary weft around warp threads and fill them in by laying in supplementary weft. The Guatemalan weavers create all kinds of bird, plant and human figures in this way.

END OF PART ONE

PART TWO:

In this part of the tutorial I show you how to create the motifs using the supplementary wefts. I am using a tree motif as the example. You will see how to create:

  • a horizontal line for the base of a tree,
  • a vertical line to form a stem,
  • filled-in shapes for leaves,
  • diagonal lines to outline the tree top, and
  • spots for buds.

This is a fun technique with little or no counting involved which allows you to play freely with shapes and colors.

The resulting weaving looks like a piece of embroidered cloth except that the “stitches” only appear on one side of the fabric.

Bookmarks made with Guatemalan tree and sun motifs

Last week when I started the tutorial on this technique, I was using acrylic threads that I had brought back from Guatemala to create bright mutlicolored trees on a green background, pictured at left.

I decided to buy some embroidery floss to work with and it took some time to get just the right thickness to go with my chosen ground weave warp. The ground weave is a 50 wpi cotton and I used 4 strands of embroidery floss to do the patterning. (one piece of embroidery floss has 6 strands so you need to remove 2).

The 50 wpi warp produces a wonderfully thin cloth just right for bookmarks although the pattern wefts do add some bulk. Remember to always use a good firm beat.

So, let’s continue with the tutorial.

All the colored wefts that form the patterns pass under or wrap around the warps in the two patterning sheds. This green piece has 86 ends between the dark green border stripes. We will start with the horizontal line that forms the base of the tree motif.

FORMING A HORIZONTAL LINE

The base of the little Guatemalan tree is a double horizontal line. STEP ONE: To form this horizontal line, place a strand of around 40cm/16″ of supplementary weft under the central patterning warp. The two ends on either side should be of equal length. The central warp in my set- up just happens to be in patterning shed 2 so I have started in the heddle shed.
STEP TWO: Cross the ends of the supplementary weft as shown. STEP THREE: Start wrapping the left hand end around the 5 warps to the left of the central warp and return wrapping around 4 warps. The diagram below shows how this is done.
The steps for horizontal wrapping are shown here. The left end of the weft wraps to the left and returns and then in STEP 4, the right end wraps to the right and returns. These four steps all take place in the same pattern shed. The wefts wrap around four warps on their return journey to the center. STEP 5: Pass the main weft through the complete shed.

This completes the base of the tree. Now I am ready to start creating the stem….a vertical line.

FORMING A VERTICAL LINE

Open the next shed, which is, in my case, the shed rod shed and pass the main weft.

Open the heddle shed and raise the patterning warps in patterning shed 2.

Patterning shed 2 contains my central warp.

Every time I raise the warps in patterning shed 2, I will wrap my green tree base weft around the central warp to form a stem. The drawing at left shows the very simple vertical wrapping method.

The stem, therefore, is woven only in every second shed.

In this shed I will also lay in the wefts to form the first pair of leaves.

FORMING A SOLID SHAPE – A LEAF

Cut two lengths of weft around 24cm/9 1/2” long for the two leaves.

I choose the position of the base of the leaf shape from the available pattern warp threads. I decide on two threads (marked above with two black dots). Note that the two marked threads aren’t adjacent. I’ll use these to create one leaf on the right hand side of the stem and also select two threads on the left hand side.
I lay the purple weft thread behind the two selected warp threads adjusting it so that its two tails are of equal length. Then I do the same on the left hand side. Now I can pass the main weft in the heddle shed, change sheds and beat.
ABOVE LEFT: I’m now in the shed-rod shed. For the second row of leaf pattern I select two warp threads from the set of pattern threads on Pattern stick 1. For the right-hand leaf I select the two pattern warp threads that lie immediately to the right of those from the previous row. I pass the right tail of weft under these two warp threads from right to left and then the left tail passes from left to right. From now on, the supplementary weft is handled in this same way. The two tails are passed behind the selected warp threads in opposite directions. Use the tip of a pointed stick to gently push them down into position. they are relaxed as they turn around the warps. Make sure they don’t pull the warps out of position as they turn around them. On the left-hand side, I select the two threads that lie immediately to the left of those from the previous row and pass the supplementary weft tails in this same way. Then pass the main weft through the shed-rod shed. Change sheds and beat.

ABOVE RIGHT: I’m now working in the heddle shed and with the pattern warp threads held on the lower pattern stick. In this row I’ll turn the green weft around the center warp to continue forming the stem. I’ll also select pattern threads that sit immediately to the right of those used in the previous row for the right-hand leaf and immediately to the left for the left hand leaf.

The drawing shows the paths of the two tails of supplementary weft from row to row. In every row the leaves advance and in every other row, the stem advances. Make the leaves as many rows as you like.
In what you’ve decided is your final row of leaf pattern, pass the right hand tail of the supplementary weft under the pattern warps as usual and then pass it for a short distance to the left within the shed before pulling it out to hang from the back of the cloth where it can be cut later. The left tail does the same…passing under the two pattern warps and then continuing to the right within the shed. In the photo above right, you can just make out the slight bulge of the supplementary weft traveling within the shed to the right of the right-hand leaf.
Starting the second leaf.

The little Guatemalan tree has three pairs of leaves and the stem continues growing until it eventually widens out into the tree top. You can see the green V-shaped top of the first tree in the photo.

Once you have woven your six leaves, I am sure that it will be very easy for you to see how the tree top is formed.

You’ve been weaving your stem with two strands of weft – to form the top, one strand will start traveling diagonally to the right and one to the left forming a solid V shape. The V shape gets filled in the same way that you “filled” the leaves.

Sometimes you might wish to just weave a little branch rather than a leaf. In that case you would just wrap the weft thread around single pattern warp threads moving out diagonally as you progress from row to row as in the drawing below right.

Finally, there are the little spots that the Guatemalan weavers like to use to fill in blank spaces between motifs. I used them in my bookmarks as flower buds. You can see two yellow spots in the photos above and below.

To make a spot, you use two adjacent patterning warps as shown in the drawing above left. Use a strand of weft half the thickness that you were using for the tree. Around  12cm/5″ length should be plenty. First place the weft behind the right-hand warp in the pair that you’ve selected making sure that the two tails are of equal length. Then join the two ends together and go wrapping them back and forth in in a figure-eight in the same shed about six times as shown in the drawing. When you’re done, pass the ends a short distance through the main shed and out the back of the weaving.

It is very easy to improvise with this technique. Have fun with it!

Backstrap Weaving – Back to a Blank Slate

This white warp provided a fresh blank slate onto which I could weave any motif I liked using supplementary weft in any color.
That matchstick screen on the right did the trick for years! Now every single wall adornment has been removed and won’t be going back up again no matter how long it takes me to sell this place and leave Bolivia forever.
Fortunately, I have some weaving shots that allow glimpses of what once was. The point of this photo was to show a silk ikat neck gaiter that I’d just finished.
This ad that I tore out of an American Airlines in-flight magazine gave me the idea to create ikat shapes and fill them with pick-up patterns.
Since my last post, I’ve washed and hard pressed this little sample and am pleased with its sheen and drape. It was quite stiff with its double amount of supplementary weft when it was on the loom. Given the improvement in drape, I’m thinking that it may work after all as a reversible neck gaiter.
Hopefully I’ll be sitting in front of a new “blank slate” warp like this soon.

Backstrap Weaving – Are Two Sides Better than One?

The teal supplementary weft travels from selvedge to selvedge of the band and you can just make out the little teal bumps along the edge where the weft exits one shed and turns to enter the next.
In this silk scarf project I used 60/2 silk as the structural weft in the sections that didn’t have pattern and changed to a 140/2 structural weft when I added the supplementary weft.
I carried the supplementary weft from selvedge to selvedge to create the patterns at the two ends of the scarf. The little flower motifs in the main body were woven using the “frame” technique.
All the samples here used the “selvedge-to-selvedge” technique except the white band with turquoise pattern second from the right. There you can see how the turquoise weft turns on the surface of the cloth to frame the pattern of triangles.
The dark brown base, stem and branches of these plant figures were created with this wrapping technique. All other parts of the patterns were created using the “frame” technique.
The upper pattern of horizontal and vertical lines was woven using the wrapping technique.
The scarf I wove using various Bhutanese motifs and two supplementary-weft patterning techniques.
You can see the front and back of this profusely patterned head sash from Aguacatan, Guatemala on the left. The back is plain red. The supplementary weft threads only travel within the shed or float on the upper face of the fabric. They never appear on the back.
This is the back of my learning piece that I wove with one of my Guatemalan teachers. You can see all the weft tails have been left hanging. They could be cut shorter and left there or snipped off flush with the fabric.
This fabric that I was told is from Chichcastenango, Guatemala is part of a huipil that has been worn and laundered over many years. You can see how the weft tails have become tangled in a merry mess on the back.
I like the back of my textiles in these techniques to be open and plain. This is the back of the paisley scarf I showed above. Creating a “clean” back is, of course, is easy to do when the supplementary weft runs from selvedge to selvedge. When there are various color changes happening across the width of the warp as there are in the Guatemalan textiles that I’ve shown here, there’ll be many more weft tails with which to deal and carefully snip at the back of the cloth.
You can see the two faces of the Guatemalan textile on the left showing the double-faced nature of this technique. On the right is my own attempt at the pair of Guatemalan quetzal birds.
This little bee pattern is the first double-faced one that I learned with my teacher. You can see that it almost looks like a cross-stitch pattern with it’s identical “stitches” stacked neatly in columns.

Backstrap Weaving – An Unexpected Match

Finished with the second figure and glad that I hadn’t cluttered the center space.
This photo gives a better view of the white-on-white pattern which is sometimes very hard to capture well. Note how the variegated thread mysteriously changes tone right at the middle of the warp.
When laid out flat like this, it’s a bit disappointing how “flat” it looks considering that it is, after all, made from silk.
Here’s another look at the white-on-white patterning on the sides that I love so much.
Here it is with one of the two flower/foliage bands placed alongside.
The two flower/foliage bands together. I was particularly pleased with these two bands as they had been a study in how to switch background colors smoothly back and forth along the length of a band without using a harsh and sudden horizontal transition.

I’ll leave you with images of two little slices of culture here in Santa Cruz…
