The \u003cb data-path-to-node=\"3\" data-index-in-node=\"175\"\u003eCreative Grids CGRT90\u003c\/b\u003e is built specifically to stop that stretch. At 6-1\/2 inches, this is the precision template for truing up your quarter-square units, ensuring the finished block lies perfectly flat without the distortion common to manual measuring.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eThis ruler isn't just a guide; it’s a locking mechanism. The patented Creative Grids non-slip grip dots are embedded across the back surface, meaning that as soon as you put your hand on the acrylic, the ruler bites into the fabric. You won't have to deal with the ruler \"skating\" across your rotary mat mid-cut. Plus, it features clearly marked 1\/4-inch seam allowance lines, so you can cut your QSTs and jump straight to the sewing machine without doing extra math.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eWhy It’s Better\u003c\/h3\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eStretch-Free Geometry:\u003c\/b\u003e Designed to align with the grain of the fabric, preventing the warping that ruins bias-heavy quarter-square units.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eInstant Seam Allowance:\u003c\/b\u003e No more \"adding a quarter inch\"—the seam lines are pre-printed on the ruler face, turning your cut into a ready-to-sew unit immediately.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eHigh-Contrast Visibility:\u003c\/b\u003e The sharp black-and-white grid pops against any fabric color, so you aren't squinting to find your alignment points.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"7\"\u003eEssential Data\u003c\/h3\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eSKU:\u003c\/b\u003e CGRT90\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eMaterial:\u003c\/b\u003e Professional-Grade Clear Acrylic\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003eAngle:\u003c\/b\u003e 90-Degree Fixed\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,3,0\"\u003e\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003eHeight:\u003c\/b\u003e 6-1\/2 Inches\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"9\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eIs this just for half-square triangles?\u003c\/b\u003e No, it is designed specifically for quarter-square triangles.

The grip technology provides a \"brake\" effect. It slides easily when you need to adjust your alignment, but holds firm the instant you apply downward pressure to cut.\u003c\/p\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003eHow does this help with bias stretch?\u003c\/b\u003e Because this ruler gives you a rigid edge to guide your rotary cutter, you are cutting against the ruler's edge rather than trying to measure along a soft, stretchy bias edge. It keeps the fabric stable throughout the entire cut.\u003c\/p\u003e","brand":"Creative Grid","offers":[{"title":"Default Title","offer_id":45932793790566,"sku":null,"price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/7872\/8294\/files\/CGRT90.jpg?v=1783912812","url":"https:\/\/threadworks.com\/products\/creative-grids-90-degree-6-1-2-quarter-square-triangle-ruler-cgrt90","provider":"Thread Works ","version":"1.0","type":"link"}
