Also...

Monday I stopped by Hobby Lobby and picked up some size 10 crochet cotton. I'm going to take the warp off the 20" RH (since it is a several-years-old project that no longer interests me) and try warping with the crochet cotton and and use the scarf yarn (from the 11" RH project) for weft. I think the carpet warp might have been a bit too thick for what I wanted when I sampled previously. So I'll probably warp that loom Friday or Saturday and try again. And with using a different loom, I won't lose any progress if I don't like it, other than time lost.

It's handy having more than one loom!
