Deflected Double Weave and Collapse Weave on 4 Shafts: How to Weave a 'Puzzle Scarf'

I call this a "Puzzle Scarf" because the two layers intertwine in a puzzling way. But the scarf is simple to weave, requiring just 4 shafts. 

The intertwining layers you see are one of the distinguishing characteristics of the structure known as "Deflected Double Weave." Unlike Double Weave -- where the layers are each woven (usually in plain weave) and sit one on top of the other -- in Deflected Double Weave, the layers are alternately plain weave and floats, with the floats being "deflected" around the woven sections. And those floats will alternately twine above and below each other, so that the two layers still form a single piece of fabric.

Collapse Weave techniques add more to the puzzle of this scarf, because without shrinking, it would look like a piece of gauze. The texture is achieved by fulling the yarn, so that the floats create woolen cords (I sometimes call them "dreads") that form interesting patterns. I love the effect and I thought I'd share the pattern on my blog -- because it's surprisingly simple.

For so many of my Collapse Weave projects, my go-to yarn is JaggerSpun 18/2 merino. Collapse Weave calls for fine yarns, and this is a lace-weight yarn at 5040 yards per pound. When it's sett loosely (another rule for Collapse Weave), the merino fulls beautifully as it's washed and agitated with hot water and soap.

Here are the instructions:

Warp: Wind a 4-yard warp (or any length you choose) of 240 ends consisting of five stripes alternating in two colors: [48 ends of color A and 48 ends of color B] twice and ending with 48 ends of color A. 

Sett: 16 ends per inch for a 15" width in the reed

Weft yarns: same two yarns as warp

Picks per inch: 16 

Here's the drawdown:

Looks pretty simple, right? Here's what it looks like as you begin weaving:

First you'll weave at least 8 picks of waste yarn as a base for your fabric. Then leave a space of about 3" before you begin weaving the scarf. (I inserted a stick shuttle to help me create a straight fell line as I began the scarf.) The waste yarn will be cut off when you have finished fulling the scarf, leaving a neat line of cords for fringe.

Begin by weaving 8 picks in plain weave. Then start layer A (mine is in burgundy), weaving 48 picks at 16 ppi. The fabric looks like gauze on the loom. But the good news is you don't really have to worry about neat selvages, since the fabric will shrink so much it won't make any difference!

Next weave your second layer (mine is in blue). Note that the selvages on both sides of this layer are 3" inside the selvages for the first layer. That's another characteristic of Deflected Double Weave: the layers don't have the same selvages. You can see in the photo below where the blue weft starts and ends. 

I recommend cutting off as you complete each color -- unless you don't mind the unruly weft yarns that you carry along between layers when they're not weaving. If you DO choose not to cut off, understand that the second layer (the blue layer here) has to start with the shuttle UNDERNEATH the burgundy layer. Otherwise, your blue weft yarn will float on top of your fabric when all the others are floating underneath.

Here's the easy part: Just keep weaving, keeping in mind that you will have about 30% shrinkage length-wise after you've fulled your scarf. That means you'll want to weave 100" for a 70" long scarf. 

When you've woven your desired length, finish as you started: weave 8 picks of plain weave in color A, then leave about 3" of warp unwoven, then weave 8 picks of waste yarn. (Again, you'll cut this off after finishing so that you'll have fulled cords for the fringe and they will be all neat and tidy.)

Now for the fulling, which is really the toughest part of making this scarf.

Wash, agitate and scrub freely in hot water and gentle dish liquid or shampoo. After the first 3 or 4 minutes of this, take it out of the water and rinse it in cold water to make sure that no parts are adhering to other parts of the scarf. (Although you want the unwoven warps and wefts to make cords, you don’t want them to fuse with other parts of the scarf, which happens when you're not paying attention.) The scarf will look messy and stringy at first, but continue to scrub, agitate, rinse and then stretch it out on a flat surface, pulling the two plain-weave sections horizontally so that they lie flat. (Basically, you are coaxing the fabric into the shape you want.)

You need to repeat this process for a while -- at least 5 or 6 times -- to get the cords to become substantial. The goal is that these floats fuse together, becoming thick and solid so that you can no longer see the individual threads.

When it's fulled sufficiently, lay the scarf on a flat surface to dry. After it's dry, cut off the waste yarn so that the fringe (which should be cords at this point) is all the same length and looks even. Iron the scarf on "wool" setting to get a smooth look, where the cords and plain-weave sections lie flat.

Snip off any single yarns that have not been fulled into cords.

There you have it! You've solved the Puzzle Scarf. 

What We Wove at Convergence: Echo Weave, Turned Taquete, Shadow Weave, Rep, Double Weave, and Even Collapse Weave

You've heard about Echo Weave, which is based on an extended parallel threading that weaves a warp-emphasis fabric with lots of color and strong patterns. But do you know about all the different structures you can weave on the same parallel threading? In addition to Echo, you can weave Turned Taquete, Shadow Weave, Rep Weave, Double Weave and even Collapse Weave, simply by changing your tieups and treadlings.

I taught a workshop on this subject last week at Convergence, the biennial conference for the Handweavers Guild of America, held this year in Reno, Nevada. "One Warp, Many Structures: An Exploration of Extended Parallel Threading" looked at all the possibilities I mentioned above. To teach this, I designed 9 different patterns -- 3 for 4 shaft looms, 3 for 8 shafts, and 3 for 12 shafts -- and invited students to choose a pattern and wind a warp using two colors of 10/2 pearl cotton. (I also named all of these patterns, using simple descriptions as a mnemonic device -- otherwise I couldn't remember them all!)

Below is a photo essay showing some of the beautiful samples the folks in my workshop created, with brief descriptions for each. It was a visual feast!

Fishing Line, Gold Gimp, and Wool/Lycra: What a Difference a Weft Makes!

You know what it's like when you're at the end of a warp -- and you decide to just throw something in to see what happens? And you LOVE the results? That's just what happened to me a few days back, as I was weaving up samples for my upcoming workshop at Convergence, "Deflected Double Weave as a Collapse Weave."

Let's start at the beginning of the warp, with a design I created for Deflected Double Weave on 8 shafts. I wove up the first sample with 10/2 cotton in purple and 18/2 merino in red in both warp and weft, aiming for a collapse effect using differential shrinkage. (The wool shrinks in the washing and the cotton doesn't, so it puckers and collapses and creates lots of texture.)

Here's the original draft.

Here's how it wove up, before washing.

I was worried, before I washed this, that it would collapse diagonally. But it didn't, because each diagonal "step," with a vertical line of red connected to a horizontal line of red, actually has two opposing vertical and horizontal lines on the back of the fabric, making a square shape of yarn that will shrink. That's the nature of Deflected Double Weave: not only do individual yarns weave plain weave -- but groups (blocks) of yarns will weave in and out of each other, as warp or weft floats.

Here's how the sample looked after washing with hot water and agitating with dish soap.

So, skipping to the end of my warp -- remember where I threw in an unusual weft yarn just to see what happened? In this case, I chose a lambswool/lycra yarn that would easily collapse. Here's what it looked like before washing.

I'm posting this photo extra-large in hopes that you can see the wool/lycra: Looking closely at the squiggly red weft yarns, can you see a bit of white here and there? That's the lycra, very loosely plied with the lambswool. It's hard to imagine it will collapse much -- but it does. A lot, to the extent that the fabric shrinks maybe 50 percent width-wise. And you can stretch it back to its original width! Here's the finished sample.

And what about the fishing line? It's also called "monofilament," and it's a great way to create interesting effects with yarns that DON'T shrink but instead make the fabric curve and undulate.

Here's the original sample, before and after washing, using the 10/2 pearl cotton and 18/2 merino in both warp and weft. (You'll note that I varied the tieup and treadling from the first draft.)

And here's what it looks like, before and after washing, substituting 14-pound fishing line for the 18/2 merino in the weft. (Picture a weaver walking into Gander Mountain to purchase weft yarns....)

Wild, huh? I can see this writ large, for a wall hanging or even a window hanging, much like a stained-glass piece that lets the light shine through. One of my favorite weavers of all time, Liz Williamson, uses monofilament as an accent weft in conjunction with a wool or other collapse weft, which makes her fabrics curve and wind in graceful and unexpected turns.

As for the gold gimp: Here's the original sample, before and after washing.

And here's what happened, shown before and after washing, when I substituted gold gimp yarn for the red merino in the weft.

Gimp is a metallic-looking yarn, typically used as an accent. (Gimp is made of a core, such as cotton, wrapped in a sparkly thread and used in embroidery and trims.)

Still more samples to weave for Convergence. This is why we don't get a lot of housecleaning done these days.... but it's way more fun. Thanks for reading!
