This is the first drawing of the full sized pattern. It's actually 1/4 of the total pattern. After looking at it and studying it for a while, I realized that the top arched segments weren't going to give me the effect I wanted. So I worked on them some more to make them look more like the original 8" design to the right of the large pattern.
This morning, I worked on transferring the pattern pieces that land on the horizontal axis to the vertical axis. This is supposed to give me complete, one-pieced pattern pieces for these segments and make it easier to stitch the pieces together. This is what the pattern looks like now.
You can see where I have redrawn some of the lines.
