The second half of the center section of my Blue On Blue quilt went together just fine. The seams matched up and I kept the blocks in order thank goodness. Now I hope that I don’t find two identical fabrics close together after it is all done. It seems like you can look and look at the blocks and then find some identical fabrics right next to each other after things are sewn together despite trying your best to look it over first. How can the eyes miss things like that when you have studied it so often?
