Use this Square on Square Trim Tool to create 4 inches or 8 inches square on square blocks. The Snails Trail blocks are now easier than ever. Trim each round as triangles are add by placing the appropriate centering square on the ruler over the center square of the block to trim two sides. Rotate the tool and the block to trim the last two sides.
Comes with fully illustrated step by step instructions.
The ruler slides easily over the fabric until pressure is applied. Then it holds the fabric in place while cutting, eliminating slipping and miss-cuts!
