I love it when something looks a little more complicated than it actually is. I had some leftover yarn from a Christmas gift I had knit and I really liked the yarn too much to leave it in my bin of discards. (Who doesn't love Malabrigo, really? Can't leave that laying around.) Even though I have been warned against weaving with single-ply for warp, I decided I'd risk it and try out a houndstooth cowl idea I had bouncing around my brain. Rigid heddles are more forgiving of single-ply and handspun yarns than their shaft counterparts (though it's not impossible to use either on a shaft-loom...if it were, there would have been centuries of naked people in history). Rigid heddle looms put yarn under less tension and often, because of the plastic heddle, are a little less abrasive to the fiber.
I warped my 15" Cricket using the full width of the heddle. I warped a 2x2 color scheme, meaning I had two teal feather warp threads then two natural warp threads all the way down the heddle. Then, with the same two colors for the weft, I had a 2x2 scheme weaving, as well. Two picks teal than two picks natural. Because there was a color change ever two picks, it was not practical to cut the thread each time, so I carried the colors. (Sometimes, if you have more than a few picks, a carry can look messy or cause a loop that can get caught on things. I found that with the 2 picks, the float carried up the side for each color change was minimal.) Tip: Choose one color on your bobbin or shuttle stick to place "in front." For me, my natural color was always the shuttle closest to my fell line. When it was not in use, I rested it either in my lap or on my woven fabric. When I was done with the teal shuttle stick I always placed it behind the natural shuttle stick before picking up and weaving with the natural color. This created a consistent look with my floats along the side of my woven fabric because the carries always overlapped each other in the same way.
I am an advocate of hemstitching fabric. Even if I plan on doing a folded hem or seam later, a hemstitch at the beginning and end of your fabric really helps hold things together when you take it off the loom. For this cowl, I ended up sewing a zigzag stitch along the hemstitch and then completely removing any fringe before folding the ends under and sewing a hem with my sewing machine. Then, with both ends neatly hemmed, I used a tapestry needle and some extra Malabrigo to seam the two hemmed ends together mattress stitch style.
I am pleased with the results. I think it was a great use of extra yarn and I had no problems with the single-ply warp.
