This only happens when I use very small needles (size 3 or smaller). For my current WIP I am using size 1 DPNs. I’m not sure how it’s happening, but I have a couple of puncture wounds on the tip my left index finger. I put a bandaid on it for a couple of days and it started to heal. But now that I’ve removed the bandaid (it kept shredding on the yarn), it’s getting worse again.
