At first, I assumed that I would sew together the half-melons and then add them to the nine patch centers, much like you add the rings to the center of a double wedding ring. I quickly found out that it was much harder. All those seam allowances at the points got in the way. So -- rip, rip, rip, let's start over. I had been concentrating so hard on the curves that I didn't think about sewing the half-melons onto the centers. Then, voila, you just have 11" square blocks to join in the regular way. Much easier.
After I completed three blocks, I had to document my progress. The colors are lovely, and the design interesting enough even though it's simple. The only thing that may be harder assembling it this way is accurately joining the points. But, you know what? I'm not going to sweat it like I did on the wedding ring quilt. I will pin and be as accurate as I can, but if a point gets a little snipped off, it's not going to make me crazy. With all those seams coming together at the points, you won't see it.
(Wow, who was that person? It didn't sound like the normal obsessive-compulsive me!)
There are 36 blocks, which comes out 66" x 66", so borders were necessary. If I had done it all nine patch blocks, it would take years! Also, since the squares come out of the fat quarter bundle, there was only enough for 36 blocks. So 36 blocks it is.
