Creative Grids 9-1/2" Triangle Squared Quilt Ruler (CGRTMT2)

If you have ever tried to piece a quilt block that finishes with a half-square triangle (HST) inside a larger unit, you know the frustration of "fudge-factoring" your seams just to make the pieces fit. The Creative Grids Triangle Squared Ruler removes the guesswork from this complex construction. Instead of sewing and trimming units blindly, this ruler is specifically engineered to let you cut, piece, and square up perfect quarter-square and half-square triangle combinations that finish at precise, clean increments.

The standout feature is the unique "Triangle Squared" design. It allows you to sew your triangles together and then trim them to the perfect size after they are pieced, ensuring your finished block is accurate to the stitch. With the signature Creative Grids non-slip backing, this template locks onto your fabric as soon as you press down, meaning you can stop worrying about bias-stretch and focus entirely on clean, sharp assembly.

Why It’s Better

• Post-Piecing Accuracy: By squaring up your triangle units after they are sewn, you compensate for any minor seam allowance variations, resulting in a perfectly flat quilt top.

• Embedded Non-Slip Grip: The translucent grip circles on the back surface act as a brake, preventing the ruler from sliding across your mat during high-pressure rotary cuts.

• Multi-Tasking Geometry: This tool simplifies the construction of complex blocks like the "Square in a Square" or "Churn Dash," handling both the math and the trimming in one go.

• High-Contrast Mapping: The white-on-black markings ensure you can clearly distinguish your alignment lines on both light background fabrics and vibrant novelty prints.

Frequently Asked Questions

Does this ruler include the seam allowance? Yes. The seam allowance is already built into the markings, so you can square up your pieced triangles to the exact finished size your pattern requires.

How does this prevent fabric sliding? The back of the ruler is embedded with proprietary non-slip grip circles. They are flush with the surface until you apply weight with your hand, which causes them to bite into the fabric and lock the ruler in place.

Can I use this for flying geese? While it is primarily designed for Triangle Squared units, the 90-degree alignment is excellent for truing up a wide variety of triangle-based patchwork components.
