Take the guesswork out of cutting half-square triangles with this Creative Grids® ruler designed by Rachel Cross. Solid black guidelines marked at 7/8in intervals eliminate the usual calculation needed to determine the correct starting-square size. Simply select the desired measurement to create half-square triangle blocks ranging from 1in to 5in finished. Easy-to-read 1in black grid lines include 1/8in and 1/4in markings for accurate alignment and cutting.

Made in the USA from high-quality acrylic, the ruler features precision measurements for quilting, sewing, patchwork, and crafting projects. Creative Grids®’ exclusive non-slip grip lets it slide smoothly over fabric for positioning, then holds securely when gentle pressure is applied to help prevent shifting and miscuts. Fully illustrated step-by-step instructions are included, and the QR code printed directly on the ruler links to a helpful how-to video.
