The lighter blue is from Rich's "shrunken" shirt (neck got too big). This is a fun quilt to make, but can get confusing getting the fence running right! I had to get my head on straight. Each 3 rail block was 4 1/2". I put them together as 9" blocks. There was a little frogging involved when I twisted the blocks. Putting together in strips might have been easier, but I probably could have fouled that up also.
