I went through my scrap jars and found all of the smallest bits, and decided to make a Ticker Tape "quilt" on canvas using this tutorial from Crazy Mom Quilts. I LOVE it so much, I think I'm going to try to win it for my sewing room...although my assistant principal has her eye on it for her office.
The biggest change I made from the method in the tutorial is that I added two coats of glossy decoupage medium on top of the fabric as well, rather than just sticking the fabric down with it. I didn't want to take any chances with the fabric edges fraying, and I like the texture it gives. The kids had so much fun placing the pieces (with a little guidance from me), and I think it will do well at the auction.
The canvas is big, measuring 24 x 36 inches, so this is a real statement piece. Even if I don't win it, I think I might have to make another one for myself!
