You will want to purchase a background fabric to make your pinwheels stand out. Also, if you purchase both the Twister and Lil' Twister Rulers and are careful when you cut your large pinwheels out an don't overcut your template by but a thread or two, you can use all of your waste to make smaller pinwheels that you could either add into your border or make a baby quilt or another project.
