I finished knitting Wisp last night, and cast off just a few minutes ago. I had to restart the bind-off several times, since mohair is not stretchy at all, and the loops kept on tightening when I was trying to do it with a smaller needle. I finally grabbed a size 10.5 US needle and bound off very slowly and carefully with it, instead of trying to make the size 8 US work. It looks a little sloppy unblocked, but I have a feeling that I'll be thankful for the loose bind-off when I'm blocking it out. Now I just need to find some lightweight buttons to sew to one end!
On a side note, I could not get this color to photograph properly. It's really a deep turquoise, but for some reason my camera reads it as cobalt, and I couldn't get it to look right in post-processing either. Which is hilarious, because I've never gotten a camera to read cobalt correctly either. Rats!
