Ideas?

OK, I know what people need here in Nebraska because the climate is very typical of the 4 seasons. However, I'm not sure what to do about a friend that lives in Oklahoma. Recently my friend R has been diagnosed with breast cancer and now it is in her lymph nodes as well. She is the mother of a beautiful 14 y/o girl who I just adore as well. I got a call from my grandmother last night that said that the chemo is going poorly and the R finally allowed her daughter to shave her head since the hair was coming out so bad. I would love to find a lacey, lightweight chemo cap pattern or an idea of a shawl or wrap that she could use even this summer. Any ideas? I'm just not sure for a warm, humid climate what would be something I could make for her. She loves anything that is handmade, but I'm not sure how much time I have to make anything. Suggestions?
