The world’s sweetest hubby bought these for me because he’s excited I’m doing something besides playing video games. I’ve only been knitting three weeks. I can’t hurt them can I? The other needle I have is stainless steel. I’m excited and grateful and sooo scared I’ll do something to them. Does anyone use them? How do you care for them? We are woodworkers and I assume they need to be oiled but won’t that ruin your yarn? I’d appreciate any advice on how to treat them.
