Do more with a single ruler, thanks to a smart folding design that can be used open as a square or transformed into a triangle. Square off corners and cut half-square triangles, rectangles or squares from 1" to 8" without fabric waste.
This sturdy acrylic ruler folds in half for more options and features a built-in 1/4" seam allowance for easy measuring. A clear, durable hinge allows the ruler to lie perfectly flat for exact alignment. Markings feature clear intersections for enhanced visibility and can be read on light, dark and patterned fabrics.
