This easy to use ruler takes the math out of cutting 1/2 square and 1/4 square triangles. It lets you cut both types of triangles from strips, rather than by cutting squares diagonally into triangles. This ruler has measurements to use strips from 1in up through 5in. Simply cut a fabric strip, then cut the triangles needed from the strip using the marked lines on the ruler that correspond to your finished size triangle.
