Key benefits — why you need this ruler Ensures precise cuts and markings: clear, detailed scale lines and accuracy reduce measurement errors and fabric waste. Versatile for pattern work: combines straight and curved guides so you can draft, grade, and alter patterns without switching tools. Durable and flexible for sewing tasks: construction balances rigidity for straight lines with enough flexibility for smooth curved lines around armholes, hips, and necklines. Product features Clear, accuracy scale: easytoread markings let you draw straight lines and measure with confidence. Curved scale for dressmaking: builtin curves and graded markings support sample making, grading, and drafting smooth seamlines. Multipurpose sewing ruler: designed for manual cutting, plate making, and general tailoring work; suitable for dressmakers and clothing measurement tasks. Durable and flexible: material and finish resist wear while allowing controlled bending for tracing curves. How it solves common sewing problems Reduces rework from inaccurate measurements by providing precise, readable scales. Speeds up pattern grading and sample construction with integrated straight and curved guides. Simplifies cutting and marking on fabric by serving as a single tool for multiple tasks. Typical use scenarios Pattern drafting: draw straight grainlines, seam allowances, and curved seam lines when creating garment patterns or grading sizes. Fabric cutting and plate making: place the ruler on fabric or pattern paper to mark accurate cutting lines for clean, consistent pieces. Garment alteration and finishing: use the curved edges to reshape armholes, necklines, and hips during alteration or when fitting samples. Compatibility and performance Intended for dressmaking, tailoring, sample making, grading, and general sewing projects. Works consistently with fabric, pattern paper, and standard manual cutting workflows. Clear, durable markings maintain readability through regular use; balanced flexibility aids precise curve tracing. What stands out Combines straightline accuracy and curveforming flexibility in one tool. Specifically designed for dressmakers and clothing measurement tasks, helping streamline pattern work and cutting. Practical tips Use a finetip marker or tailor's chalk along the ruler edge for crisp lines. Support the fabric on a flat surface for the most accurate measurements and cuts. Clean gently to preserve the clarity of scale markings and extend tool life.
