The overlock machine, often referred to as a serger, is another crucial piece of equipment in any sewing studio. Its primary function is to trim and finish fabric edges simultaneously, preventing fraying and ensuring that garments last longer. Overlock machines use multiple threads, typically between three and five, to create a secure seam that stretches along with the fabric, much like what a coverstitch machine does but on a different scale.
coverstitch overlock machine4. Durability and Build Quality Given the nature of what you’ll be working with, a robust construction is non-negotiable. Look for machines made from high-quality metal components, which will stand the test of time.
3. Build Quality The materials and craftsmanship that go into a sewing machine significantly impact its durability and performance. Machines constructed with high-quality materials, such as metal frames and components, are generally more expensive but offer greater longevity and stability during use. For those planning to use their machine frequently, investing in a higher-quality model may pay off in the long run.
The presser foot holds the fabric against the machine’s feed dogs, assisting in its smooth movement as stitches are formed. The pressure exerted by the presser foot needs modification depending on the fabric’s thickness. Light fabrics require gentle pressure to avoid stretching or distortion, while robust fabrics might necessitate firmer pressure for efficient feed. Machines that allow for presser foot pressure adjustments allow users to customize this crucial point of fabric-machine interaction, ensuring optimal fabric feed and reduced sewing mishaps.

6. Warranty and Support Comprehensive warranties and customer support options can also influence pricing. Machines that come with extended warranties and responsive service are generally more expensive as they reflect the manufacturer's confidence in their product.


In addition to regular cleaning, it’s important to oil your heavy duty sewing machine according to the manufacturer’s instructions.
