I do the pinwheel where I can JennyPenny, but this different! I tried to go to your link Aunt Piggy, but it said "unhandled excemption." I think Tartan's is the way - I just tried to change the directions of the way I had pressed the seam, to get the seams to nest, and I had a real mess. Plus, I repositioned some of the blocks all together and now I am just ripping along! Me and my best friend!
