Knit fabrics can be challenging to sew with a regular sewing machine because they stretch. A serger excels in this department; it not only sews the fabric together but also stretches with it. The differential feed feature, found in most sergers, allows you to adjust the feed dogs for various fabric types, ensuring that your seams don’t pucker and your projects maintain their intended shape.

For those who work extensively with knit fabrics, overlockers are particularly beneficial. They can create elasticized seams that stretch without breaking, a crucial feature for items like t-shirts, dresses, and activewear. This flexibility not only enhances comfort but also improves the overall fit of the garment, elevating the end product's quality.

Moreover, automatic bag closer machines contribute to cost savings. By reducing labor requirements, manufacturers can allocate resources more efficiently. The high-speed operation of these machines leads to shorter production cycles, allowing businesses to meet demand without the need to overstaff. This streamlining of operations is particularly beneficial for companies looking to scale their production while controlling costs.

1. Tension Settings Adjusting your sewing machine's tension settings may be necessary when using heavy-duty thread. A loose tension can cause loops and poor seam quality, while too much tension can break the thread. Perform a test stitch on a scrap piece of canvas to find the right balance.

Lock sewing, often referred to as “lock stitch sewing,” is a technique that utilizes two threads—one from the needle and the other from the bobbin—to create a secure stitch. The stitches interlock at the seam, making it less prone to unraveling. This method is widely used in both industrial and home sewing machines because of its efficiency and the neat finish it provides.
