Lockstitch is the familiar stitch performed by most household sewing machines and most industrial “single needle” sewing machines from two threads, probably one passed through a needle and one coming from a bobbin or shuttle. as a result, each thread stays on the same side of the material being sewn, interacting with the other thread at each needle hole by means of a bobbin driver. As a result, a lockstitch can be formed anywhere on the material being sewn; it does not need to be near an edge.

Jack OverLock MAchines

Overlock also is known as “serging” or “serger stitch”, can be formed with one to four threads, one or two needles, and one or two loopers. Overlock sewing machines are usually equipped with knives that trim or create the edge immediately in front of the stitch formation. Household and industrial overlock machines are commonly used for garment seams in knit or stretchy fabrics, for garment seams where the fabric is light enough that the seam does not need to be pressed open, and for protecting edges against raveling. Machines using two to four threads are most common, and frequently one machine can be configured for several varieties of overlock stitch.

    How do I use serger thread on a regular sewing machine?

      Hello Radhika,
      Thank you for visiting our JJ Sewing Machine Website.
      Serger thread is designed to be used on a serger, period. It is much finer and more elastic than regular thread. If you wind it onto a bobbin it will not wind with the proper tension which will result in poor stitches in your sewing. It is also much “lintier’ than machine thread. This will cause issues with your tension discs and under your bobbin.
      The most outstanding reason not to do this involves your needle. Sergers have different needles than sewing machines, they’re made to accommodate serger thread. Your sewing machine needle will be wrong in every conceivable way for serger thread. Stitch quality will suffer and your finished product won’t look nearly as nice.
