WOW! What gorgeous quilts! I especially like the Black & White version with the three different sized blocks. It really was a novel idea for the border. The top quilt with all the black center squares really takes on a different look when you added the smaller squares connecting the larger squared sets. Your multicolored one is very bright. You used several different colors for the center squares as well. What were the size of the four patch blocks in the black & white one? Were the other two quilts made with the same size blocks?
