I am looking into making my own knitting needles and was wondering about dowel sizes. Now, I have done the dirty work in calculating (or actually just googling mm sizes). I am asking someone who has had experience in making these things, have you had to use the same size dowel for a needle? For example, I am finding that sizes 3, 4, and 5 looks like they will be the same (and those are sizes I want as DPNs). I also know that precision won't be in this case.
Any advice is appreciated.
