Do you know the technique of sewing a smaller square diagonally into the corner of a larger block to get that pop of color in the corner? The Corner Pop tool allows you to get the same result with half the little squares with great results and more options. Using the lines on one side of the tool you trim the larger block first. Seam allowances are already incorporated into the configuration of the tool. No math is needed!

Using the included chart, you cut the smaller square slightly larger and then in half diagonally. Each square results in two triangles, rather than having to cut a square for each of the four corners. Where have these tools been my whole life?
