Multipurpose curved drafting aid designed to assist with scaled pattern design and toile making. Incorporates shaped curves that make drawing sleeve holes and similar pattern openings faster and more consistent. Outer curve line measures 41 cm. Key benefits Improves accuracy: provides a reliable curve for sleeve holes and related pattern lines so drafted pieces match intended shapes. Saves time: speeds up drawing and adjusting curves compared with freehand drafting. Flexible use: designed for work with scaled patterns and toiles across garment types. Features and important attributes Primary function: multipurpose work aid for scaled pattern design and toile construction. Compatibility: suitable for pattern drafting, toile fitting, alterations and any workflow that requires repeated curved lines (sleeve holes, armholes, curved seamlines). Size: outer curve line measures 41 cm, giving a long, usable sweep for many sleeve and armhole sizes. Performance: provides consistent, repeatable curves to help maintain proportional accuracy in scaled patterns. Practical use scenarios Drafting a bodice toile: use the curve to mark sleeve holes and ensure consistent armhole shape across sizes before cutting fabric. Alterations and fittings: redraw sleeve openings on a toile to test changes quickly and accurately without freehand guesswork. Scaled pattern work: reproduce the same curved lines when grading or transferring scaled designs to different pattern sheets. Specification Function: multipurpose curved drafting aid for scaled pattern design and toiles Notable measurement: outer curve line = 41 cm Use this tool to standardize curved lines in your patternmaking process, reduce drafting time, and improve consistency between iterations.
