Moreover, the versatility of the overlock chain stitch extends beyond clothing. It is often used in the production of home textiles, such as curtains and upholstery, where a neat finish and the ability to handle varying fabric types are required. This stitch can also be found in the crafting of accessories, like bags and hats, where strength and elasticity are vital.

When selecting strong sewing machine needles, it’s crucial to consider the type and weight of the fabric you will be working with. For instance, a size 90/14 heavy-duty needle is suitable for thicker fabrics like canvas and upholstery, while a 100/16 needle can handle even tougher materials. Additionally, it’s important to match your thread type with the needle; for example, using heavier thread with a needle designed for thicker materials ensures that both components work harmoniously.
