Neat tool helps you create fast triangles
The size of this tool surprised me - it's over a foot long. The goal of the tool is to help you create 1/2 or 1/4 square triangles (think two-tone squares as the final product). It gives the size you need to cut the squares, directions for sewing, and instructions for how to make these up to a fairly large size. I haven't used it yet as I don't use a lot of 1/2 or 1/4 square triangles. Not as fast as the foundation piecing method but less hassle and easier to follow.
