This set contains a so-called kite-form and a crown-form. Six kites together make a hexagon, and three crowns also make a hexagon. This set has a finished size of 3 inch, side of the hexagon. In combination with template set H, you can make endlessly more patterns.
You can use this set to make charm quilts (one form repeated), but you can also make the beautiful Rose Star block, using a combination of the two templates.
The book accompanying the set, contains instructions for a quilt with the Rose Star block.
