A Few Questions AnsweredFriday, April 08, 2011
Hopefully this image with help clarify were the pintucks go and why I added the 5" squares to the center of the 10" squares. You could just mark the pintuck positions with dots but the lines and boxes were helpful to me so that I could keep everything lined up straight. If you decide to use the template method like I did I used all the line on the grid to line my template up to making it very visually easy to everything square.
Hopefully this was helpful and I answered all of your questions.
