A slip stitch is a basic sewing technique used to join two pieces of fabric together or to finish edges. It is often employed in hand sewing and knitting to create a nearly invisible seam. The stitch is made by passing the needle through the fabric and pulling the thread through, without creating a knot, allowing for a smooth finish. In knitting, a slip stitch can also refer to a technique where a stitch is moved from one needle to another without being knitted. This method can create interesting textures and patterns, often used in knitting patterns and crochet projects.
