I think this a wonderful idea. I crochet a lot, and already have more hats and scarves than I can wear. (Not needed much in Southern Virginia). Those might be nice gifts that would cheer patients up, and would be useful. Let me know if you would like me to help.
I am about to have my own surgery on my tongue (not a major one this time). They are going to, of course be doing another biopsy, and I am fearing the worst. Even if my worst fears come true with that, I will have a lot of down time, and can do a lot of crocheting.
