My six year old was diagnosed with Stage II non-Hodgkins lymphoma last month. So far he's doing great with the chemo, including he hasn't missed a day of 1st grade. What can you tell me about an interesting hat that I can make for him now that we cut off all his hair. (We had to cut it all off. He was walking around school, pulling it out and giving it to people. Some thought that was funny, others thought it gross, many found it distracting.) Any way, who can make a recommendation for a type of yarn that would be comfortable but warm and a pattern that's more interesting than ribbing. I've checked Ravelry, but nothing stands out. What can you guys recommend?
