A dear friend has just started chemo to treat breast cancer. I'd like to make her a hat as a small gesture of support. I'll also cook for her freezer etc and do housework when I can visit (we live away).
I've read that cotton yarn is the best for this purpose, and have some on order, but a lot of the patterns I have seen are pretty plain and boring. Does the hat need to be plain, or could I incorporate patterns or cables? Any insight gratefully accepted.
