The Dritz Serrated Tracing Wheel is used for marking multiple layers and bulky fabrics.
The pro tip
Work on hard protected surface and mark wrong side of fabric only.
Use with tracing paper to transfer pattern markings for darts, pleats, tucks, pockets, and buttonholes to fabric.
The bottom line
Will transfer markings through a double thickness of most fabrics. Makes dotted markings on most fabric.
