The Creative Grids® Simple 7/8" Triangle Maker Quilt Ruler (CGR78) is a highly specialized, premium acrylic template designed to completely eliminate the complicated math and cutting errors associated with making half-square triangles (HSTs). By allowing you to cut the precise seven-eighths of an inch fractional measurement directly from fabric strips, this innovative tool guarantees that your pieced triangle blocks square up perfectly to their exact finished sizes every single time. Key Features Patented Non-Slip Embedded Gripper Backing: Features exclusive micro-textured gripper tracks on the reverse side that anchor fabric firmly under downward cutting pressure, yet slide smoothly across layouts when relaxed. Streamlined 7/8-Inch Fractional Cutting: Eliminates complex math by providing direct, clear cutting lines specifically engineered for standard half-square triangle construction. High-Contrast Dual Markings: High-visibility solid black lines combined with crisp white dashed grid marks guarantee absolute readability across dark, light, and complex multi-colored patterned textiles. Pre-Cut Strip Compatibility: Designed to work perfectly with standard fabric strip widths, making it incredibly fast to sub-cut multiple triangle pairs consecutively. Laser-Smooth Edge Durability: Constructed from extra-thick, industrial-grade premium acrylic that guides rotary cutter blades flawlessly while avoiding blade nicks and edge degradation. Why Customers Love This Ruler To make standard half-square triangles from squares, traditional quilting logic requires you to add seven-eighths of an inch to the finished block size and cut squares diagonally. Finding that exact fractional line on a traditional multi-purpose ruler is a recipe for eye strain and slipping miscuts. The CGR78 solves this layout issue by isolating the exact measurement you need into a dedicated, rock-solid template. It stops fabric shifting completely, giving you clean, flat-set trims and saving expensive yards of fabric from ruinous miscuts. Perfect For Quilters who make traditional half-square triangles, star blocks, and multi-piece geometric patchwork. Artisans frustrated by the tedious micro-math of adding fractional seam allowances to finished design units. Sewists looking to maximize fabric yields from strip packs, jelly rolls, or scrap collections. Makers searching for an ultra-reliable, specialized geometry template that speeds up mass block cutting workflows. Included Accessories Creative Grids® CGR78 Simple 7/8" Triangle Maker Ruler Step-by-step illustrated instruction manual explaining calculation rules and cutting steps for perfect half-square triangles Specifications Brand: Creative Grids® Model Number: CGR78 Purpose: Half-Square Triangle Construction Increments: Optimized for 7/8-inch fractional additions Material: Heavy-duty, premium-grade laser acrylic Country of Origin: Made in the USA Frequently Asked Questions Q: Why do I need a specific 7/8-inch ruler for cutting triangles? A: Standard quilting math dictates that to cut squares and slice them once diagonally to create half-square triangles, you must add 7/8 of an inch to your desired finished block size. Finding this exact line on normal rulers is difficult; this ruler has it built-in explicitly to save you time and prevent cutting mistakes. Q: Can this triangle maker ruler be used safely alongside standard rotary cutters? A: Yes. It is manufactured from the exact same thick, industrial-grade acrylic used across all standard Creative Grids® templates, ensuring your fingers remain safely guarded when tracking with 18mm, 28mm, or 45mm rotary cutter blades. Q: Will the non-slip grippers on the back snag or wear out delicate fabrics? A: No. The patented gripper design utilizes smooth, micro-textured friction tracks molded directly into the acrylic structure rather than abrasive sprayed-on grit or sticky film. It provides maximum holding power without snagging fabrics or leaving adhesive residue.
