Lovely MN knitters, how do you avoid getting 'lines' when you knit with dpn's? I'm attempting to knit a hat with dpns rather than traditional needles and I can't work out how to avoid the change in tension when I swap needles. I've tried holding the needles at funny angles, knitting the first few stiches on the 'old' needle and then swapping them to the new but nothing seems to work. Has anyone got any advice on how to avoid this? Thanks.
