knitting in the round help

[lullabymoon]

I've just finished my second hat, and I've run into the same problem with both. They both seem to spiral slightly and I can't figure out why. This is only the second time I've knitted in the round so I could be missing something fairly obvious.


(the cast on edge is straight, my model was getting rather annoyed at my fidgeting).

My marker stayed in the same position and I wasn't moving the rib along. It's not blocked, and I hadn't planned on blocking it as it'll face the rain regularly, but I'm not sure that would help anyway. Does anyone have any idea what I've done wrong?

ETA: Thanks for all the help, with it I've discovered I've been knitting into the back of the stitch instead of the front which has caused the twisting.

Are you using a singles yarn or does it have multiple plys? Singles yarns can bias like that. Also, is it a fiber that can be blocked--such as wool--and have you blocked it?

No it's a multiple ply. Both the hats can be blocked but I hadn't planned too on this one as it will get soaking wet in the winter. I tried blocking the first one but it didn't help much.
