My summer project is to do some more experimentation with leno and gauze
weaves. One thing I wanted to try is to push the boundary of how light
and airy I can go with this structure, so I am trying some very fine silk yarn.
I also thought that with all
the different angles the yarn takes, it might be a candidate for
iridescence. The real proof will be when I get it off the loom, but I
think it is happening: here are photos of the fabric on the loom from
two different angles. One angle is showing the reddish weft more, and the other the blues in the warp. This fabric is plain gauze, with each pair of warps twisting the same direction at the same time.
