Crochet twisting as go along

[ruthybaby]

When I crochet something in a long line, for example a scarf, it twists round as I go. I was hoping crocheting a couple of rows onto the foundation chain would help, but it just becomes more obvious. I think it may be something to do with my tension, but I'm not really sure how to solve it. Does anyone have any ideas or suffer from the same problem?
Thankyou

I find that tight stitch patterns will do this... maybe go up a hook size or two?

I run into this problem whenever I crochet too tightly (which is almost always).  A bigger hook should help quite a bit.  You could try blocking it a bit when it's done too, which might help get rid of a bit of curl.

I also prefer to use foundationless stitches for something like a scarf. I find a normal foundation chain often goes tight. If you can use a foundationless base to get started, it keeps the whole thing looser.
