Overlock stitch instead of serger - I had no idea! Did you know that most regular sewing machines have a special overlock stitch that mimics a serger's stitch? It's true! My Bernina has one, and so have the Pfaff and Brother machines I've sewn on. Most people without a serger use pinking or zigzagging to finish their edges, sometimes without even knowing they have an overlock stitch on their sewing machines.
