When my sister went through chemo I made her an entire wardrobe of Fleece hats. They keep the head warm and cover the loss of hair very nicely and there are many free patterns on the internet. They only take a few minutes and she loved the fact that she could match whatever he was wearing with a different hat! When she passed away her local Hospice asked her husband if he would donate all her pretty hats to them for other cancer patients. He did and I still make them for our local cancer patient care center.
