Worsted / Aran Cotton Yarn

Worsted cotton works up fast on US 7–8 needles and washes in the machine, which makes it the yarn for market bags, dishcloths, baby blankets and the summer sweater that wool is too warm for.

Cotton has no spring, so ribbing relaxes and a long cardigan can stretch: knit it a little tighter than the ball band, or pick a cotton-wool blend such as Cotton Fleece that bounces back.
