Precision Hemming Made Easy: Features laser-cut marking holes at exact intervals (1/4" and 5/8") for precise fold measurements every time. The width ensures consistent, professional-quality hems on all fabric types, from delicate chiffon to heavy denim. Unmatched Heat Resistance: Made from industrial-grade silicone that withstands iron temperatures up to 230°C without damage. Stays cool to the touch immediately after pressing and won't stick to or scorch fabrics like traditional metal guides. Compatible with all iron types, including steam irons. The tool can curve in either direction, and even in both directions at once—ideal for shaping shirt tails. Use the holes to mark your position with chalk or an iron-off pen. Flexible Yet Stable Design: Provides stability during use while the flexible material easily follows straight edges and curved seams. Non-slip surface holds fabric securely when pinned and works well with tailor's hams for shaping curved areas. Ergonomic & User-Friendly Design: Lightweight yet durable construction helps reduce hand fatigue during extended sewing sessions. Rounded edges prevent fabric snagging, and the smooth surface allows easy fabric adjustment. The flexible material can be rolled for compact storage in your sewing kit.
