Are there any moms crocheting hats for breast cancer patients?

You might see if you local library will sponsor you and other people in this effort. Ours has and evening a week that the community room is set up for people to come and learn to knit or crochet (or mentor) and make squares that are then put into comfort bankets.
The library has flyers and posters for us and a basket that anyone can drop off squares or yarn or tools if they like. Yours might do something like that as well.
If you are willing to teach you might contact a local girl scout troop that might want to learn, do a community service project and earn a badge.
