When knitting with cotton I strongly urge you to knit tight and evenly. While wool is wonderfully sproingy cotton likes to drape and does not have the same elasticity.

I tend to knit loose and fast. Here I used size one needles and still I had to be mindful of tight, tight knit and purl stitches. If you tend to knit on the tight side then all of this is a moot point.

Enjoy!
