The Peachtree Flexible Curve Template allows for the precise duplication and transfer of complicated and/or compound curves from patterns or work pieces. Simply Align the curve template to the curve that you wish to transfer, and then tighten the template's handy locking knobs all along the spine of that curve; the curve will hold in the template which will then allow you to transfer the pattern to whatever material you are working on. Locking the knobs eliminates any movement or “creeping” that typically happens with other pattern transfer devices.This process is ideal for perfect shape matching. Maximum bendability allows for a wide array of replicable shapes. Ideal for use with metal, wood, plastic, leather and fabric, etc. Innovative, effective, and so simple to use!
