All-in-One Drafting Solution: Integrates a straight-edge ruler, set-square, and multiple French-curve sections (necklines, armholes, hems) into one 16" tool—streamlining pattern drafting without switching instruments. Quickly add 1/4”, 1/2”, or 2.5” seam allowances – no more mental conversions!

1/16" Precision Top-Edge Scale: Finely etched sixteenth-inch markings along the top edge allow on-the-fly seam allowance adjustments, dart placements, and style-line grading with sub-quarter-inch accuracy.

Premium 3mm Non-Yellowing Acrylic: Crafted from professional-grade 3mm thick acrylic that maintains crystal clarity over time, ensuring lasting transparency for precise pattern tracing and marking.

Exclusive 60° Angle Lines: Features unique 60-degree angle markings not found on standard pattern rulers, perfect for creating geometric designs, precise darts, and technical pattern alterations.

Enhanced Readability Design: Enlarged scale markings and high-contrast etching provide superior visibility in all lighting conditions, reducing eye strain during long pattern-making sessions.
