mmm - a few kinks needing help ...
Despite the areas that need improvement, I'm amazed the technique is still in my noggin. My Add-a-Quarter ruler has disappeared over the years, so that was replaced, then I had to purchase and install a new printer (for copies of pattern), and my little old Bernina needed an extension table (wonderful improvement in efficiency). Trying new things does not always turn out perfectly. (But don't those outer points look good!) Not sure why I dislike this layout - those corners seem to be the problem - maybe just a regular square would be better? It still looks like some creepy fossil thing that lives in a rock. Feel free to pipe in with opinions about colors or layout or ? ( I recognize the crummy seam. )
