You might want to investigate further. A lot of time the Quilt Branch patterns are using their rulers to make their quilts. I bought several books and a ruler. I found it difficult to use them without taking a class. When she was demonstrating it looked so easy. I was too lazy and unmotivated to learn to use the ruler. I looked at the patterns and figured out an easier way to make the quilt. I agree that her books and patterns look great. I put the ruler on the free table at our guild and kept the books. So check and see if it requires her rulers. In fact, I have purchased some of her books twice. Silly me.
