I think it would be good to get the rulers since you already cut some 2 inch strips. They were quite inexpensive with a Joann's coupon..I think it would cost about 8 dollars total if you had someone use a coupon while you used one. I ordered initially from amazon and it was much more expensive. Do you have a Joann's near you? It looks much simpler using rulers and less fabric waste, but I'm impressed with those who did it without!
