Fits the Following Models Flexible Curve Ruler — designed for DIY clothing supplies and related patternmaking tasks. Key benefits Accurately captures and reproduces smooth, irregular curves for patterns, drawings, and templates. Flexible enough to bend into many shapes yet firm enough to hold the chosen curve for tracing or transfer. Transparent construction and clear line markings make alignment and placement simple on paper or a drawing board. Raised edges guide pens and inks for cleaner, more consistent ruling. Main features Material: durable vinyl plastic — wear resistant, will not fade or decompose with age. Flexible but not flimsy: bends to required shapes and maintains position for tracing and transferring lines. Raised edge design for ink ruling and neater line work. Slim profile fits easily on a drawing board and stores flat or curved as needed. Performance and reliability Vinyl construction resists wear and retains clarity over time, supporting repeated use in sewing, drafting, and field work. Clear line visibility helps reduce errors when aligning patterns, drawings, or layouts. Practical use scenarios Dressmaking: Shape collars, armholes, waist seams, and other garment curves when drafting patterns or adjusting fit. Drafting and engineering: Trace smooth transitions and contour lines on plans or technical drawings where straight rulers can't follow a curve. Construction, surveying, and craft work: Create templates for trim, moldings, signage, or modelmaking where precise, repeatable curves are needed. Quick notes for users Works well on drawing boards and flat surfaces; press gently to hold shape while tracing. Suitable for a broad range of applications: drafting, engineering, construction, surveying, dressmaking, and crafts.
