Loretta posted a link to an antique doll quilt site and there was a beautiful checker board quilt there that I just loved.
So, I reproduced it for myself with different colors in my program. I was thinking of mixing and matching all different colors in one or just maintaining it as two colors.
I don't like sharp contrast, so I muted it a bit. This design isn't for everybody, but for me it's appealing.
