Ha! It turns out I can't us 12 inch squares anyway. I am making this from scraps of another quilt I made for the Boys' Ranch, and it turns out that the biggest scraps I have will make 9 inch squares. So I am now playing with a smaller square, which I am pretty sure will look good anyway, just not the mental image I had. Often my mental image doesn't end up working out....
So I am now playing with 9 inch squares...48 instead of 35. I was going to try to get a pattern going, but it may be completely random now. I have 4 sports fabrics and 5 solid or blender fabrics.
Still, should be fun to play with.
