Understanding Lock Stitch on Sewing Machines

The type of presser foot that comes with a sewing machine can make a significant difference in sewing thick materials. Look for machines that offer a range of presser feet, such as walking feet or Teflon feet, specifically designed for heavy fabrics. A walking foot helps to feed multiple layers of fabric evenly, while a Teflon foot glides smoothly over sticky materials like leather or vinyl.

The Role of Technology

At its core, a serger machine is designed to finish the edges of fabric. It combines several functions—trimming, sewing, and overlocking—into one operation. Unlike a traditional sewing machine, which typically uses a single needle and one or two threads, a serger can use multiple threads (usually 3 or 4) to create a secure seam. This capability allows it to produce stitches that not only hold layers of fabric together but also prevent fraying and unraveling.
