If pattern lines are to be transferred on paper or fabric, the tracing wheel from the prym.ergonomics series is a useful sewing accessory. While the smooth tracing wheel draws a solid line, the Prym toothed tracing wheel draws dotted lines on the material or pattern paper. The wheels are characterized by a quiet and smooth running and can be run perfectly on every line. Also marks in cut sections, such as tucks or pocket positions can be transferred simply using the Prym tracing wheel and tracing paper.
