Precision Hemming Made Easy: Features laser-cut marking holes at exact intervals (1/4" and 5/8") for precise fold measurements. Ensures consistent, professional-quality hems on a wide range of fabric types, from delicate chiffon to heavy denim. Unmatched Heat Resistance: Constructed from industrial-grade silicone that withstands iron temperatures up to 230°C without damage. Remains cool to the touch shortly after use and does not stick to or scorch fabrics, unlike traditional metal guides. Compatible with all iron types, including steam irons. Flexible Yet Stable Design: Offers stability during use while conforming easily to both straight edges and curved seams. Can curve in multiple directions simultaneously, ideal for shaping shirt tails and other curved hems. Use with chalk or washable marking pens to transfer measurements through the holes. Non-slip surface holds fabric securely when pinned and works well with tailor's hams for shaping curved areas. Ergonomic & User-Friendly Design: Lightweight and durable construction helps reduce hand fatigue during prolonged use. Rounded edges prevent fabric snagging, and the smooth surface allows easy repositioning of fabric. The flexible material can be rolled for compact storage in any sewing kit.
