One of our church ministries is to provide quilts to cancer patients at the local hospital. So far this year we have donated 137 comfort quilts and 7 knitted prayer shawls (a group of about 15 women). I make mine 40-42 wide by 62-65 long, depending on the block size and how wide my backing material is! We can always use more so if you can't find a local source, they will be greatly appreciated in North Carolina. I have developed a couple of controlled scrappy patterns that are the perfect size and doesn't cost an arm and a leg to donate. The guild buys the batting and if money is available, muslin for the back. And I beg scraps off anyone I know in order to keep the work going. The majority of my scraps are cut 3 1/2 x 6 1/2 in order to take advantage of the scrappy patterns I like the most. Here is a link to my favorite
