The La Passacaglia quilt by Willyne Hammerstein requires 5 shapes. This set includes the templates of 100 pieces of each cardstock shapes to use. Therefore you get 500 shapes of card templates making it easier to be more accurate. This is the medium size and not the original size in the book which is 1/4 inch smaller. Now you don't need freezer paper and can re-use these templates provided they have only been lightly glued. Preferably not using pritt but a glue stick or basting without piercing the paper.
