A slip stitch is a basic sewing technique used to join two pieces of fabric together or to finish edges. It involves passing the needle through the fabric without creating visible stitches on the front side, making it ideal for hemming or closing seams discreetly. This technique is commonly used in hand sewing and can also be applied in knitting to create a seamless look. In knitting, a slip stitch can refer to a specific stitch where the yarn is passed over the needle without being knitted. This method can create interesting textures and patterns, often used in designs like slip stitch patterns or colorwork. It is a versatile technique that enhances both the functionality and aesthetics of knitted items.
