So... I'm knitting a pair of socks and I've found several painful bumps on my fingers. I don't think they're blisters because a month or two ago I was knitting small ornaments very tightly and no such thing happened. I've been knitting more this weekend because we had a long power outage and these bumps have gotten very irritated so my guess is it's the yarn? Has anyone had any problems when using Premier Yarns: Deborah Norville Collection sock yarn? Or maybe when using purple yarns?
