Struggling with my next warp sett. Still weaving the moiré effect but now with a 2 coloured warp. Same yarn as first warp. That warp was sett at 6 per cm. Did the same with this one but the weave structure is different, being waffle, so after having the warp ready for weaving I changed my mind and rethreaded to 8 per cm. After weaving I thought I did not like it, so unwove and rethreaded again at 6 per cm. But when weaving, I knew that the sett was wrong, so out it came again and I'm now ready again to start weaving at 8 per cm. Never before have I had this problem. May be waffle is just not the right weave structure for me. Still all part of the guild workshop, so I will finish weaving it. Not a very long warp! :-) This 2 coloured warp will weave waffle and twill that should show moiré effect.
I did make photos before unweaving, so I can see the difference.
