After seeing your tutorial, I made a 15" 4 patch into a d4p. It ends up 13" and is easy to trim to 12 1/2". I did it at 4 a.m. without much sleep and messed up on the cutting twice, so I had the 2 lights in a corner and the 2 main colors in another corner, but even with messing it up, from a distance it looks nice so decided to keep it. Showed the ladies at my bee and they loved it too. Thank you so much for your tutorial.
ps. I think these are addictive. I'm already thinking of the way I want to make more. lol
