I just PMed with Auburnchick and I am really excited about participating for the next set of blankets.
I didn't read every post in the thread, but if there are still suggestions being taken about where to donate blankets to, one I am thinking of here in Boise is the City Light Shelter. In Boise, we don't have enough resources for the homeless, and most of the ones we do have are for men. This shelter helps women and children. I think it would be neat to consider it as a cause.
If anyone would like me to, I am happy to contact them and ask about what their needs are.
