Wedge weave is a type of weaving style that gives a distinctive look as the “rows” are woven diagonally. According to what I’ve read, this style of weaving may have become less popular as buyers of rugs wanted a straight edge, and this gives a very unusual scalloped edge due to the way the weft pulls against the warp. There are many different ways to use this style, and some weavers drop in a little here and there while others weave this way for the entire project.

My little sample, about 4″ x 5″, worked out okay for a first try. I learned how to start and stop threads, add new colors, and carry a pattern. I also found out that the loose threads should be woven back in otherwise they’ll pop through to the front. I have some floats here and there, as I puzzled through how to reverse directions. I wove this on a Goodwood Pocket loom.

And off the loom. I was pleased to see that even with my loose and sloppy weaving, the scalloped edges came through:
