Ergonomic adjustable 'mouse' tracing wheel for tracing seam lines and/or cutting lines at either 1.5cm, 2.5cm (1") or 4cm.
This is a fantastic tool for marking out accurate lines - like seam allowances or bone channels. It works by distributing a very thin line of loose chalk onto your fabric. You can even do curved lines if you like! It's a two part system featuring a main chalk wheel and a tracing wheel which runs parallel and is combined with the adjustable measuring unit.
