When you are piecing 60-degree designs, even a quarter-degree of error means your points will blunt and your quilt won't lay flat. The Creative Grids CGRT60 is engineered to eliminate that geometry struggle. At 8-1/2 inches tall, it provides the perfect vertical clearance to slice equilateral triangles and diamond units from standard fabric strips without having to constantly pivot or re-measure.
The secret to this ruler’s performance is the embedded non-slip grip. We know how standard acrylic can slide when you're making long, diagonal rotary cuts. This ruler features patented translucent grip circles on the back that bite into the fabric the second you apply your hand's weight. It stops the ruler from "kicking out" at the end of a cut, which is exactly where most triangle points get ruined. With 1/4-inch seam allowances pre-marked on both sides of the center axis, you aren't just cutting shapes—you're cutting ready-to-sew components.
Key Features
-
Precision 60-Degree Geometry: Engineered to create perfect equilateral triangles, ensuring all three sides are mathematically equal for seamless, ripple-free assembly.
-
Ideal 8.5-Inch Height: The perfect scale for squaring up standard patchwork blocks, trimming hexagon units, and cutting multiple triangles from standard fabric strips.
-
Exclusive Non-Slip Perimeter: The entire outer edge features the patented Creative Grids translucent grip coating, which anchors the ruler to your fabric the moment you apply downward pressure.
-
Built-in Seam Allowances: Includes clearly marked 1/4-inch seam allowances on the vertical center axis, allowing you to cut perfectly sized pieces that are ready to sew.
-
High-Visibility Markings: Crisp black and white dashed guidelines make it easy to align the ruler on solid light cottons, dark solids, and busy, patterned novelty fabrics.
-
Durable Acrylic Construction: Machined from thick, high-grade acrylic that resists warping and chipping, providing a stable, straight edge for even the most repetitive cutting tasks.
Why Customers Love This Tool
Quilters specializing in geometric designs like the "Tumbling Block," "Star of Bethlehem," or "Hexagon Flower" patterns rely on this ruler to solve the most common geometric piecing frustration: shifting fabric. Most standard rulers are slippery, which is dangerous when cutting long, tapered triangles. Customers love that the CGRT60 stays exactly where they place it, preventing the ruler from kicking out under the pressure of the blade. Furthermore, the 8.5-inch size is incredibly versatile—it's large enough to handle most block needs but compact enough to manipulate easily on a crowded sewing table.
Perfect For
-
Equilateral Triangle Piecing: The essential template for constructing crisp, uniform triangles for geometric quilts.
-
Hexagon & Diamond Construction: Easily slice the building-block units needed to assemble large hexagons and 3D-effect diamond patterns.
-
Stitch-and-Flip Geometry: Ideal for quick-cutting the 60-degree units required for modern "star" patterns and sawtooth border variations.
-
Fussy Cutting: Use the vertical center lines to perfectly frame and center fabric motifs, creating stunning kaleidoscopic effects in your pieced units.

Frequently Asked Questions
Does this ruler include the seam allowance? Yes. The 1/4-inch seam allowance is already factored into the dimensions, so your cut pieces will be ready to sew into your pattern without needing to add extra math.
Is this easy to use for beginners? Absolutely. The high-contrast black and white markings make it very clear where to align your fabric. Because the ruler locks onto your fabric with the non-slip grip, it is much easier for beginners to make safe, accurate cuts than it is with traditional, slippery rulers.
Can I use this ruler to cut diamonds? Yes. Because diamonds are composed of two 60-degree triangles joined together, you can easily use this ruler to slice the equilateral units needed to construct diamonds and hexagons.
