There are several ways to join blocks for the quilt-as-you-go method. One way would be to do the opposite of what I have here, to join the strips to the back and front the other way up, and to end up with just hand hemming on the back. That's what I did with the baby quilt shown previously. But I decided to join these blocks a different way. This is how I joined the blocks together. I cut two strips, one for the back of the quilt which is 1 1/4 inches wide. I put the other strip on the front, and it was cut 2 inches wide and pressed in half (the long way.) I pinned the back strip to the edge, as shown in the first photo. And on the other side of it, I pinned the front strip to the same edge on the front of the block, as shown in the second photo. You now have a strip pinned to each side of the edge. Sew in a 1/4 inch seam. The third photo shows that the strips have been sewn. Open out the back strip and sew another block to it. You will now have the two blocks in place, and will only need to cover the seam with that top strip. Fold it over and sew it down. I just used a machine zig-zag stitch.
