Old shale diagonal - decreasing corner

This is one option to square the top and k2tog side of Old Shale diagonal 2 fabric. You could also center it around the k2tog dip rather than the YO arch, but then it would be impossible to make a square with the OS diagonal and the OS increasing corner.

I'm not sure why, but Stitch Maps refuses to repeat this.
