Overedge Stitch: A Triangular Seam Finish for Clean, Durable Edges
Meta Description: An overedge stitch creates a triangular-shaped seam allowance, often trimmed to the correct width with shears. Learn how this stitch prevents fraying and strengthens fabric edges.
What is an Overedge Stitch?
An overedge stitch is a seam finishing technique where the seam allowance is shaped into a triangle and trimmed to the appropriate width using shears. This technique is commonly used to prevent fraying, reinforce seams, and provide a clean, professional edge.
It is often performed using an overedger (serger) or a specialized overedge stitch setting on a sewing machine.

✔ Trimmed to the Appropriate Width – Excess fabric is cut with shears or a serger’s built-in blade.
✔ Prevents Fabric Fraying – Helps reinforce raw edges and maintain garment durability.
✔ Used in Knitwear & Woven Fabrics – Common in apparel, upholstery, and industrial sewing.
✔ Works Well for Stretch & Delicate Materials – Provides a neat, flexible seam finish.
