can you recommend cotton yarn for a hat?
I've been making various "chemo caps" for my cousin who is being treated for advanced breast cancer. (She's only 42--it's an awful situation. Her mom died of breast cancer when she was in her early 50s, our mutual aunt died in her late 50s from breast cancer, and my mom died in her 50s from ovarian cancer. We've got to keep on working foor a cure.) She has no hair due to the chemotherapy, and the caps should be really soft and washable.
Anyway, my cousin really likes the caps, but as we head into spring she would like some which are less warm and bulky. I had been using a cotton/acrylic worsted (or just acrylic) of various sorts (Bernat denim (I think that was it!), velour, frizzy eyelash yarn, Caron's soft worsted).
Could you please recommend some really soft cotton or cotton-blend yarns which would work for a roll-brim or ribbed-cuff basic hat? I looked at the balls of cotton yarn in the local hobby store and they seemed kind of stiff or scratchy.
How can I make a less-warm hat without making it too breezy or hole-y?
I already knit very loosely (and then compensate with smaller needles).
Thanks for your help.
