Achieve precise 1/4 inch seams every time: this straight ruler template is designed to give quilters consistent, professional seam allowances for accurate piecing and repeatable results. Durable acrylic construction: clear, hardwearing acrylic provides visibility of fabric and markings while resisting wear for longlasting use. Works where you need it: use the ruler directly on your cutting mat or while guiding fabric at your sewing machine to mark and measure without shifting. Nonslip grip surface: textured backing keeps the ruler stable during measuring and cutting, reducing slips that cause inaccurate seams or wasted fabric. Ideal for unmarked diagonal lines and bias work: quickly mark or align diagonal lines without drawing full templates, and create accurate bias seams for betterfitting corners and blocks. Mitered corners and square piecing made simple: designed to help you form precise mitered corners and join squares with consistent bias seam allowance, improving block alignment and finish. Clear visibility improves accuracy: the transparent acrylic lets you see fabric prints and seam lines beneath the ruler so you can position and cut with confidence. Lowmaintenance and reliable performance: easy to clean and store, the ruler maintains its shape and measurements over time. Use scenarios: Quilting a sampler quilt: use the ruler to cut multiple 1/4 inch seam allowances and assemble blocks with matching seams and accurate mitered corners. Constructing biasbound edges: align the ruler to mark unprinted diagonal lines and piece strips with exact bias seam allowances for tidy binding or borders. Piecing squares and halfsquare triangles: place the ruler on fabric or a cutting mat to accurately trim and square up blocks without shifting fabric under your rotary cutter or at the machine.
