According to the directions in the pattern you just cut along one side first to get the wedges listed. Then you do the next two stratas to get the wedges listed. Then they say to go back and use the scraps to finish cutting. I do mine different and I cut both sides of the first two stratas before I go on to the next two. You will just have to practice and see what works for you. I used old fat quarters I had around the house before I used my good fabrics so if it messed up I wouldn't be out any money.
