1 inch Width Pattern Drafter, when you need a wide seam allowance for fit adjustments. A one inch seam allowance that has a french curve and straight edge allows you to let out the sides (if you need to) of the clothes you make for growth and fit. Save time chalking out your patterns. The long straight edge is great for hems and shirt plackets.

This ruler isn’t just for pattern drafting — it’s a multifunctional sewing essential that keeps your lines clean, your curves consistent, and your designs professional.
