Understanding a Serger or Overlocking Sewing Machine

By Debbie Colgrove, About.com Guide

A machine with differential feed gives you more options. When you are working with knits, you can adjust the feed, to obtain the same results that you would with an even feed foot on your regular machine. When working with a single layer of woven fabrics, you can "speed up the feed", to create a ruffle. You can also adjust the machine to create a waved edge (lettuce leaf) effect.
