Wonderful of you to do this and be a supportive friend. This post came in very handy for me as my niece was diagnosed just 3 weeks ago with ovarian cancer. She had surgery two weeks ago today and has been back to the hospital 2 times since with complications. Chemo is scheduled to begin Monday and I have been with her 12 hours a day through this and will continue to be with her through her chemo. She was told she will loose her hair and I have been thinking about hats for her.
Thank you for being a wonderful friend and for posting this request for patterns.
Also, thank you all for responding.
