Now that the planning is done, you are ready to start doing the math needed to help us make a puff quilt.
You start by measuring from inside seam to inside seam. I didn’t add the sewn edges because I have a special use for those later that will save us a lot of time in the end. Did you just guess binding? You smart thing!
My sheet measures 109″ X 89″. It isn’t exactly standard because each manufacturer decided the size of their individual sheets on their own. After you measure your sheet without the seams, you have to figure out the size of your middle layer of squares. By playing with the numbers, I discovered that 109 divided by 20 equaled 5.45 and 89 divided by 17 gives me just about the same number. This means I can cut 6 inch squares and have plenty of room for a seam allowance. The seam allowance is the amount of space between where you start sewing and the edge. Because I divided it by 20, I’ll have 20 squares across the top of my quilt and 17 going down the side. Multiply those two numbers and you’ll see how many squares you’ll need to make total. 20 X 17 = 340 squares.
