Creative Grids Quilt Ruler (6½” Square)

If you only have room for one square ruler, this is a strong contender. The 6½” size is versatile enough to trim blocks, prep HSTs, and square up almost anything.

It’s easy to read with clear black and white markings, including 1/8”, 1/4”, and ½” increments. Dashed ¼” seam allowance lines are printed on two sides. The diagonal line helps line up half-square triangles, and a center cross makes squaring up four-patches and appliqué blocks simple.

It glides when you want it to and grips when you press down. No shifting, no guesswork, just clean cuts and consistent results.
