I am involved with Relay also! I made a lap size quilt out of my stash and raffled it off. We did $5 per ticket or 5 for $20. We raised under $100. One thing I found out is that some people will like a memory type quilt, others won't. If you do a general quilt pattern/colors, you might get more donations for it. If you could, do 2 quilts. That is my goal for 2012 Relay to make at least 2.
Good luck!
