Fons & Porter Half and Quarter Ruler

Cut perfect triangles from strips measuring 1-inch to 5-inch in width!
This easy to use ruler takes the math out of cutting half-square and quarter-square triangles. It lets you cut both types of triangles from strips rather than by cutting squares diagonally into triangles. This is a special ruler for scrap quilts because you use strips of even-inch or half-inch widths! Ruler features an acrylic construction with easy to follow black and yellow markings.
