That warp that had the snapping problem (individual strands of Noro sock yarn are delicate!) was transferred in a big clump from the Ashford table loom to my trusty Glimakra Emilia rigid heddle loom. The only thing that didn't go wrong was that I was smart enough to tie a knot at the top so I knew just where to put a warp stick. That's all that I did right. 🙂 But leave it to good ol' Emilia to take a mess and make it work out (knock on wood). Even though the warp is still a mess with tangled threads, I simply wound it on very gently and threaded each slot and hole with two strands using the 8 dent heddle. If one strand breaks, I'm still good to go. I'm using a pattern stick to create some warp floats. I think it shows off the pretty Noro colors a bit more than plain weave.
The weft is black crochet cotton, very thin and strong. I decided to use one of my slim poke shuttles, and it's working out great. Because it's small and nothing catches on it, it's perfect for a sticky warp. So far, I really love how this is turning out. But I would not recommend using Noro sock yarn as a warp unless you know what you're getting into.
