Square Squared Ruler
Finally a tool that simplifies the construction of the Diamond Square unit without having to use paper foundation piecing. It is an all-in-one tool that gives you a window template for accurately cutting the center square, a chart printed right on the ruler for the recommended size to cut the triangles sewn to the four sides of the center square and a trim down section on the ruler that simplifies the alignment of ruler to fabric unit and allows everyone to clean up the unit to a precise measurement every time.
