The price of a three-thread overlock machine also depends on the market demand and competition. In a competitive market, manufacturers may offer discounts or promotions to attract customers, which can result in lower prices for consumers. On the other hand, machines that are in high demand and have limited availability may be priced higher due to the law of supply and demand.

These machines are generally robust to withstand the high speed and repetitive action of sewing, thus ensuring longevity and reduced downtime. The head of the sewing machine is the heart of the operation, housing the needle, bobbin, and other vital components that work in unison to deliver a reliable performance.

3. Interlocking with Bobbin Thread The bobbin case, which holds the bottom thread, is designed to catch this loop. As the needle continues to move up, the loop tightens around the bobbin thread, creating the lock stitch. Once the loop is locked in place, the needle continues its downward motion, pulling the newly formed stitch tight against the fabric.

2. Multiple Stitch Options Beyond the zigzag stitch, many precision machines come equipped with various stitch patterns that expand creative possibilities. Decorative stitches, buttonhole stitches, and even quilting options provide a wealth of choices, making it a worthy investment for anyone passionate about sewing.

2. Stretch and Recovery The stretch characteristics of coverstitch seams allow the fabric to move freely. This is especially crucial for athletic wear and fitted clothing. The coverstitch's ability to stretch with the fabric means that seams are less likely to pop during wear.
