These were made using that strip method cutting on a 45 degree angle. I won't fib and say it was easy. It was challenging for sure. I liked this pattern because it matched the outer tips with the center, all others I've seen don't do that. I did just get a book on making them without diamonds she uses hst and rectangles, that way there aren't any set in pieces. I think I'd have more trouble matching up the 100's and 100's of hst's.
Thank you all for the nice comments.
