Wow! Thanks for all the helpful responses.
I have tried this on all of the needles I have. The scarf is currently on the circulars, I have a set of bamboo dpn's, and a set of cheapie plastic needles. It did the same thing on all of them. They are size 10 and a half.
It probably is my tension when I knit I tend to tighten up the yarn after each stitch.
I have asked for a set of interchangeables for my b-day, and trying to decide which I want (not until November, so I have some time).
Is there a guide photo I can look at somewhere that shows what proper tension should look like?
I will try to loosen up the stitches and see if that helps!
Thanks again! Everyone on this site is so friendly and helpful!
