The fashion and food documents are a 'guideline' for Family Studies teachers in developing and operating a program that will prevent and control incidents. Such a program will protect students and increase the effectiveness of instructional methods and facilities. Both documents do not supersede national or provincial legislation and procedures.
The flat edge, narrow edge, or flat hem setting is used to finish fabrics that are too heavy for the rolled edge to work well. The looper threads meet at the edge of the fabric, creating a balanced stitch. The fabric edge will still roll slightly to the underside.
Flatlocking can be used as a decorative stitch. Most sergers can flatlock if they have a two-thread or three-thread capability, but the tension range of some sergers may be too limited to sew perfect flatlock stitches.
Rolled Edge: may be called rolled hem, narrow rolled edge, felling stitch, roll-over stitch, handkerchief hem, lapping stitch, curling stitch, or folding stitch.
The wrapped stitch is good to use on fabrics that don't ravel easily but are too heavy to roll (as in the rolled edge or flat edge). The wrapped stitch may also be called a binding stitch or reversible edge. A two-thread or three-thread stitch can be used.
