Here's one I haven't seen before. If you look down the left side of the page, you'll see a link that tells how you can donate quilts for auction. They must be 9x12 (I think). You can do your own design, or with permission, someone else's design. I'm trying to get permission to do another of my "White Tie" cat quilts. As I look at the gallery, it looks as if it would be an appropriate entry--and easy enough for me! Check it out:
