I have done a couple of raffle quilts -- the one that was fastest was a big block (24" sq) in the middle like a medalion. It was a star and I did 4-patches in the corners with a focus fabric in the middle. I then had all kinds of fun alternating plain and fancy borders. I did it in red white and blue and it brought in a lot of $$$. I made it 60x80 (since I was asked at the last minute and had less than a month to make it).
