What are sergers (aka "overlock machine")?
Sergers are finishing machines that cut and finish the raw edges of the material (fabric) one is sewing. Unlike a straight-stitch sewing machine, sergers use loopers to make the stitch, and a set of knives (one on top that moves against the bottom blade) like a pair of scissors when cuting.
Sergers give garments a finished look in much less time than it would take with a regular sewing machine.
Shopping for a serger...
If you are looking for a serger -- as a first- time purchase or a replacement -- go to the store or online shopping site armed with knowledge on the subject! You'll be able to start narrowing down the field to find a serger that will make your sewing faster, neater, and more efficient.
Sergers, also called overlock machines, create professional factory-like stitches similar to those seen in ready-to-wear garments. If you know how to use a serger, they are huge time-savers because they let you sew about two to three times faster than standard sewing machines. Further, sergers can replace three operations with one step by sewing, cutting, and overcasting a seam all at once.
There are five types of serger machines:
For best evaluation of how a serger will work for you, plan to test-sew the type of fabrics you use most often. It’s best bringing along some stretch knits as well as a variety of woven fabrics. Put together a set of representative swatches for each serger machine you want to try and use the Serger Evaluation Form (below). Sew (and label) samples, take notes, and then do your own comparison.
