What is tracing used for in sewing?
It is used to transfer markings from sewing patterns onto fabric with or without the use of tracing paper, and can be used to make slotted perforations. Such markings might include pleats, darts, buttonholes, notches or placement lines for appliques or pockets.
What is used in transferring lines to the fabric if tracing wheel is used?
Dressmaker’s tracing paper is made to be used with your choice of tracing wheels. It is a special waxed carbon paper that is placed between fabric and the pattern (with the colored side facing the fabric) and then transfers color onto the fabric along the path that your tracing wheel takes.
