I have the same dilemna. . . I have a rainbow of colors so what I decided to do is tones - the current one has 24 gree/blue/brown pinwheels and I am going to make it a 'boys' quilt. I plan on donating mine to a kids hospital. This one would be more teenage boy- I have some juvenile prints to use for younger boys , pinks/res and yellow for the girls. That was my solution. Will post them as I get them done. I have a total of 50 pinwheels - but needed a break. Anyone else have an ideas??
