A set of two clear acrylic slotted trimmer rulers (A & B) for squaring up half square triangles quickly and accurately.

Line the marked seam line on the ruler up with the seam of your unpressed half square triangle, trim along the slot and the edges, and every unit comes out the right size with the seam running exactly corner to corner. Ideal when you have lots of triangles to trim.
