What is flatlock stitching? What is the difference between coverstitch and overlock? In this video, I will show you what a flat stitch looks like and how it differs from an overlock stitch. The cover stitch machine has three needles and one looper. Overlock has two needles and two loopers. Therefore, their stitches are completely different. The overlock stitch is used for overcasting fabric sections. The cover stitch machine is used for hemming the bottom of T-shirts, sleeves and hemming other sportswear.
