My Diamond Dilemma

I so want to start working on some diamonds, but for the life of me, I can't decide on fabric. Linda Franz made her Quilted Diamonds with just two fabrics, white and blue. My first thought was to make scrappy diamonds, then, I could use my test diamond. Now, I'm thinking the scrappy look would not do the diamonds justice. I could go with just two colours like Linda, or I could select one of the many fabric collections, for a little more variety in the diamonds. As for colour, I'm now thinking soft and feminine. What would you do?
