I am working on a set of 54" wide pieces made out of zephyr. I measured one I had made in the past and came up with about 15% shrinkage so that is the number I used. I just washed the first piece off the loom and measured it and there was practically no shrinkage at all (in fact, it seems to have grown a bit in width...). Anyone have experience with how much zephyr shrinks or if there is a trick to get it to shrink a little more? I wet finished in warm water. I'm hesitant to go hotter since I don't want to risk my colors bleeding onto the white background, but now I have two pieces that are larger than I wanted and I am still a bit cautious about making the third one smaller.
