Understanding a Serger or Overlocking Sewing Machine

By Debbie Colgrove, About.com Guide

A serger trims the seam and encloses the seam allowance or edge of the fabric, inside a thread casing, all in one step. The width and density of the stitching are two of the many variables available on a serger. The options are not the same on all sergers. As with almost any thing you purchase, the more you spend, the more options you will have.
