Compatibility Model: The Sewing Ruler is For DIY clothing supplies Key benefits — why you need this ruler Makes pattern drafting faster and more accurate: draw curves, angles and seam allowances with consistent results. Reduces trialanderror when fitting garments: clear markings and smooth curves help produce professionallooking patterns. Durable and flexible construction means it withstands regular use without losing shape. Main features material: made from plastic with clear line markings; wear resistant, bendable but not flimsy. Clear, standard scale: measurements are easy to read and reliable for pattern work. Multiple functions in one tool: draw hip curves, armhole curves, sleeve curves, 45° and 90° angles, and straight lines. Seam allowances: quickly add 0.5 cm or 1.0 cm seam allowance to curves or straight edges. Symmetry and layout: measure and draw equal distances on either side of a center line. Smooth curve control: various curves can be easily drawn by simply turning the ruler, making sleeve and contour design simple. How it solves common problems Eliminates uneven curves and inconsistent seam allowance that lead to fit issues. Speeds up pattern adjustments and grading by letting you mark angles and allowances precisely. Avoids fragile tools that deform; the ruler is bendable for ease of use but holds its shape for repeatable results. Practical applications / use scenarios Drafting a sleeve pattern: use the ruler to draw accurate sleeve cap curves, measure equal ease on both sides, and add the required 0.5 cm or 1.0 cm seam allowance. Altering a bodice or skirt: create smooth hip and armhole curves, check 45° and 90° angles for darts or facings, and lay out seam allowances before cutting fabric. Home sewing and DIY clothing projects: quickly mark straight lines for hems, align pattern pieces, and refine contours when designing garments. What to expect in everyday use Clear, easytoread lines that speed marking and reduce mistakes. A single, versatile tool that replaces multiple specialty rulers for curves and angles. Reliable performance for patternmaking tasks, especially useful when designing sleeves.
