The Wonders of a Double Tracing Wheel | NotionsThis clever gadget lets you mark your seam allowances at the same time that you trace a garment.
Trace garments or patterns and add accurate seam allowances at the same time with Clover’s Double Tracing Wheel.
This tool is equipped with two adjustable marking wheels. Place the wheels in your choice of seven holes along the plastic handle’s top edge to reflect metric seam allowances in 0.5 cm increments between 0.5 cm and 3.0 cm. Although this tool was designed for the metric system, you can adjust your sewing easily to reflect the chosen seam-allowance width.
Clover’s Double Tracing Wheel available from Amazon.com.
