Okay, I'm making a super-huge scarf on a bamboo circular and a pair of fingerless mitts on bamboo DPNs. This is the first time I've ever worked with bamboo for an extended period and I'm starting to dislike it. It's great that I'm not slipping stitches off the end of my needles, but after a while my fingers start to feel... tingly. It's like... over stimulation of the nerves or something, I don't know, but when it happens I have to stop and wait until the sensation goes away. It doesn't hurt, though, it's just really annoying. Has anyone else experienced this?
