Turn fabric strips up to 8-1/2in wide into accurate half-square triangles with the Creative Grids® 45 Degree Triangle Ruler. Designed by Rachel Cross, this versatile quilting ruler features a trimmed top tip, allowing you to cut coordinating triangles and squares from the same fabric strip. Horizontal guidelines marked every 1/4in accommodate a range of strip widths, while a dashed 1/4in seam allowance surrounds the entire edge for clear, consistent alignment.

Made in the USA from high-quality acrylic, the ruler combines precision measurements with easy-to-read black and white markings for quilting, sewing, patchwork, and crafting projects. Creative Grids®’ exclusive non-slip grip lets the ruler glide easily over fabric while you position it, then holds firmly when gentle pressure is applied. Fully illustrated step-by-step instructions are included, along with a QR code linking to a helpful how-to video and patterns made with the 45 Degree Triangle Ruler.
