What it does: a transparent, metric sewing and patternmaking ruler designed for fashion pattern drafting, dressmaking, quilting and general patchwork. Use it as a pattern making ruler, quilt sewing template, dress maker's ruler or clothing drafting tool. Key benefits: Faster pattern creation: clear metric markings and guide lines speed up marking, grading and drafting so designers and sewists complete patterns more quickly and accurately. Improved accuracy: precise, easytoread graduations reduce measurement errors and help maintain consistent seam allowances and grading across pieces. Smooth curve tracing: flexible sliding and curvefriendly sections make it simple to trace collars, sleeves, armholes and other intricate garment lines with controlled, repeatable curves. Multipurpose compatibility: works on paper patterns, fabric, interfacing and plastic templates — suitable for dressmakers, tailors, quilters and craftmakers. Important attributes: Transparent plastic construction for unobstructed visibility of pattern lines and fabric underneath. Metric measurement system for standard, precise drafting and grading. Includes straight edges, square references and curved segments to handle both linear and curved pattern work. Designed for repeated use in pattern marking, quilting supply layouts, and sewing template work. Typical applications: 1. Garment drafting and grading — mark seam allowances, draw style lines and grade sizes with clear metric increments and curve guides. 2. Quilting and patchwork — align blocks, mark seam lines and use the transparent template to position pieces before sewing. 3. Template tracing and alterations — trace patterns onto fabric or paper, adjust curves for fit changes, and transfer accurate markings for production sewing. Why buyers choose it: Combines the functions of a pattern making ruler, quilting template and dressmaker's ruler into one tool. Makes pattern marking faster while keeping measurements exact, reducing rework and fitting problems. Clear, metric markings and curvefriendly design support professional results for hobbyists and working designers alike.
