Creative Grids 12-1/2in Square Quilt Ruler – CGR12, Non-Slip Acrylic with High-Contrast Markings

The Creative Grids 12-1/2in square ruler (CGR12) is a precision acrylic quilting tool with an exclusive non-slip grip for accurate measuring and cutting of quilt blocks.

This compact square ruler is engineered for quilters, sewists, and crafters who need a reliable tool to trim and square the most common block sizes. Made in the USA from stable, clear acrylic, it features high-contrast markings, centre lines, and diagonal guides to speed up cutting, trimming, and aligning. The Creative Grids non-slip technology lets you position the ruler and apply light pressure to keep it steady while you cut, reducing shifting and improving repeatable accuracy.

How does this ruler make trimming quilt blocks easier?

The CGR12 is designed to simplify squaring and trimming by combining clear centre guides and precise grid markings with a tacky surface that resists movement. The 45-degree diagonal and dashed seam-guides let you align half-square and pieced blocks quickly, while the printed centre lines ensure consistent placement.

• 12-1/2in square size fits the most popular block dimensions.
• White centre lines for fast squaring of four-patches and appliqué work.
• 45-degree diagonal and 1/4in dashed lines for accurate seam trimming.
• Clear acrylic with high-contrast black and white markings for visibility.

What measuring increments and features does it include?

Markings are printed in an easy-to-read one-inch grid with finer 1/8in and 1/4in subdivisions so you can measure and cut with confidence. Creative Grids adds a Turn-a-Round system: use white numbers on black dots and the 1/2in grip sides for cutting half-inch increments without guesswork.

• Grid printed in 1in with 1/8in and 1/4in increments.
• Black numbers on white dots and white numbers on black dots for alternate measurements.
• 1/4in grip sides and 1/2in grip sides for different cutting modes.
• Total dimension: 12-1/2in × 12-1/2in—fits standard rotary cutters and mats.

How does the non-slip grip work and why is it helpful?

The Creative Grids exclusive non-slip grip allows the ruler to glide into place and then hold when slight pressure is applied, preventing shifting while you cut. This means fewer trimmed errors and cleaner edges, especially when working with multiple repeats or bias edges.

• Grip surface holds the ruler steady without adhesive residue.
• Allows precise cuts with rotary cutters or craft knives.
• Reduces fabric slippage for more accurate seam allowances.
• Durable acrylic maintains grip properties through normal use.
