If you don't have a serger, there are a few other options for finishing raw edges and preventing fraying on a dress. Here are some alternatives seam finishes to consider: Most commonly used Zigzag Stitch: Most sewing machines have a zigzag stitch. Set your sewing machine to a narrow zigzag stitch and sew along the raw edge of the fabric. Overcast Stitch (Mock Overlock): Some sewing machines include a foot or an overcast stitch for this purpose. It performs the same function as an overlocker/serger. Could be useful French Seam: It is a stylish way to conceal raw edges that are commonly used in lightweight fabrics. Flat-felled Seam: Flat-felled Seam, like French seam, is a type of enclosed seam that conceals the raw edges within the folds. Straight Stitch: This method involves sewing a line of straight stitches along the tiny folded raw edge. Binding with Bias Tape: Bind the raw edges with bias tape to seal them. Hand Overcasting: You can hand-sew overcast stitches by wrapping the thread around the raw edge to prevent fraying. Rarely used in garments Pinking Shears: Although not as secure as other methods, cutting the raw edges with pinking shears can reduce fraying.
