Hi! This pattern is sewn from 36 strips that are 2 1/2'' wide and 40'' long. The strips are sewn together in sets first, and then cut into the blade shape above. You will need a total of 2 1/2 yards of fabric in as many prints as possible. Fat quarters will not work since you need 40'' long strips. A jelly roll bundle with 36 or more strips is perfect. Good luck!
