My friend Christine of My Sweet Potato 3 has created a Cancer Challenge for everyone that crochets/knits! She just recently lost her Uncle to cancer and wants to honor his memory by spreading some love to other cancer patients out there. She has offered a coupon code for her Ravelry site for one free pattern. All she asks is that you make a minimum of one hat for a Cancer patient. If you can’t make one yourself you can always sponsor a hat that she will make for you.
Please check out her blog post to get more info about the challenge as well as the coupon code for your free pattern.

Thank you so much Robin! I am overwhelmed with the response in this challenge and having so many other crocheters/crafters out there helping to spread the word helps so much.
