OK so I have been looking at diffrent dpn's. I think metal would be better when going that small a diameter.
Now what length? I have no idea. I thought 6 or 7 inches would be good for making socks. I do own a set of US 2 that are 4 inches long. I have made a pair of socks with them, my first pair, so I know it can be done. Yes I know I previously posted that I knew what length, but now I am reconsidering.
Anyone have any ideas, that is if anyone is reading this that is a knitter.
