7 clear acrylic templates. The templates in Set A are based on a 3" (7.6 cm) finished square and its most common component parts. Those in Set B are the same geometric components of a square, but are based on a finished 4" (10 cm) square.
Any patchwork block you can make with Set A templates can also be made with Set B; it will just be larger. Every template has its own permanent identifying number. The collection of patchwork blocks featured in Volume 1 is keyed numerically for use with the corresponding Perfect Patchwork Templates. The versatility of the templates means you can make several block sizes from each set of templates.
