I just did the same thing. My husband and I run a small Italian Greyhound rescue and a couple of weeks ago, we got in a 6 month old female who needs her back knees completely re-built. (no kneecaps- genetic). So we needed to raise $1500. I decided to raffle a quilt. Doh! My solution was to make a whole cloth quilt with just an applique of an Italian greyhound. I found this fabulous sheet in a discount store for $3.99, matched a sheet for the back and quilted it. It took me a while, but nearly as long as if I'd had to piece the entire top. Just a thought.
