Creative Grids Simple 7/8" Half-Square Triangle Ruler CGR78

Designed by Rachel Cross. Creative Grids Rulers are made in the USA and sold through independent quilt shops as well as select online retailers.

Take the math out of cutting half-square triangles with this ruler designed by Rachel Cross for Creative Grids by adding 7/8" to the finished size. Easy to read 1" black grid lines with 1/8" and 1/4" marks. Solid black lines are marked at 7/8" intervals taking the math out of figuring what size square to start with. Half-square triangle blocks finished sizes range from 1" to 5".

The Creative Grids non-slip grip lets you position the ruler on the fabric, then helps hold it steady when pressure is applied for cutting or marking. It comes with illustrated step-by-step instructions. Scan the QR code printed on the tool or instructions to watch a how-to video and see patterns made with it.

Creative Projects You Can Complete

Prepare starting squares for half-square-triangle units without repeatedly adding the 7/8-inch allowance by hand. Use matching units for pinwheels, star points, sawtooth borders or scrappy patchwork.

Choose a supported finished size and follow the corresponding starting-square marks. Check the instructions and your seam allowance on a sample pair before cutting an entire quilt; use the printed allowance marks to keep repeated starting squares consistent.
