I took a workshop and we made a quilt using the Fibonacci number sequence. It was a weekend of pure brain hurt. I remember a square divided in two squares and then we added the two sizes together to get the next square and so on. Lots of numbers. I forgot the instructor's name but she was a math geek and had a good class. I gave up the math part and cut the squares to fit as I thought looked right. My quilt looked the same as the others that did the math problems. I trusted what I thought looked pleasing and had a better time sewing.
