What is the difference between a 3-thread and 4-thread overlocker stitch?

• A 3-thread stitch is primarily used for finishing raw edges and creating narrow seams. It's great for lightweight fabrics and for creating a professional look on seam edges.
• A 4-thread stitch provides more strength and durability because it includes an extra row of stitching, making it ideal for construction seams on garments and medium-weight fabrics.
• A 5-thread is an additional option to look out for, which includes an additional chain stitch, ideal for heavy fabrics like denim or for more industrial-quality seams.

While it's not as strong as a 3 or 4-thread overlock, the 2-thread stitch is perfect when you need something lightweight and less visible. It's all about having the right tool for the right job, and this stitch can make your projects look polished without being too heavy weight, leaving you with a soft finished edge.

• A 2-thread overlocker stitch uses just two threads to create a simple, but effective stitch that trims and finishes the fabric edges. The 2-thread, 1-needle stitch is lighter and less bulky, making it ideal for some specific uses.
