The Mini Geometrics set includes five pieces for cutting six shapes, including a 3/4" hexie. The shapes work independently and with other  sets of Perfect Patchwork Templates. For example, with templates 79, 80 and 81 there are 22 blocks in Volume 1 of the Encyclopedia of Patchwork Blocks that can be made. However, all 69 blocks can be made in 3", 4", 4 1/2", 5", 6" and 8" sizes by incorporating some of the smaller pieces in Sets A or B with Set N templates.
Template 82 is a 45-degree diamond with 1" sides. Combine it with Templates 79 and 80 to make the cutest 3 1/2" (9.2 cm) eight-pointed star and many other blocks in Volume 3.
Template 78 is a hexagon with a 3/4" (1.9 cm) finished side, just in case the 1" (2.54 cm) hexagon in Set G isn't small enough! This template set includes a 60-degree equilateral triangle that coordinates with the hexagon. Both pieces can be integrated with the hexagon family in Set H.
