Form curve ruler designed for garment design, pattern making, and fitting adjustments. Clear inch markings along the edges and a thin profile make it easy to measure and draw smooth, repeatable curves for armholes, necklines, sleeves, and shoulders. Key benefits Accurate measurement: Clear inch markings along both edges let you measure while drafting or cutting patterns without switching tools. Smooth, repeatable curves: Specially shaped edges help you draw and modify armholes, necklines, sleeves, and arms for cleaner lines and more consistent results. Betterfitting patterns: Use the ruler to adjust shoulder, sleeve, and neckline curves on paper patterns to improve the garment's fit to the human body. Versatile and easy to use: Suitable for tailors, dress designers, pattern makers, and beginners working on drafting, alterations, or final pattern layout. Important attributes Function: Drawing and modifying garment curves; measuring during drafting and cutting. Compatibility: Intended for garment design tasks — ideal for tailors, beginners, dress designers, and pattern makers. Size: Approx. 21 cm x 61 cm x 0.1 cm (8.27 in x 24.02 in x 0.04 in). Performance: Thin profile and edge markings enable precise tracing and smooth curve transitions. Practical use scenarios Drafting a custom dress: Trace consistent armhole and neckline curves that match client measurements while keeping proportions balanced across pattern pieces. Pattern alteration: Blend and redraw sleeve caps and shoulder seams on paper patterns to refine fit before cutting fabric. Teaching and learning: Demonstrate and practice drawing standard garment curves in patternmaking classes or workshops.
