Utility stitches and practical sewing select Shell-edging Shell-edging is attractive on thin, soft fabrics such as silk and Bastiste. It is often used as a decorative edging on lingerie. The higher the needle thread tension, the deeper the shell edge scallop. • Serge the fabric edge and iron the seam allowance to the left. • Take care that the fabric only runs half underneath the presser foot while sewing. This intensifies the effect of the shelledging.

A fine fabric of another color can also be used instead of a woollen thread. Just lay the heavy thread against the edge of the fold and let the zigzag swing of the stitch catch the heavy thread forming a scallop. 2:8
