Knitter's Stitch is a type of stitch used in knitting. It is also known as the PURL stitch, which is a four-letter word that can be found in crosswords. The PURL stitch is used to create a variety of textures and patterns in knitted fabrics. It is created by looping the yarn around the needle in the opposite direction from the knit stitch. This creates a bumpy texture on the fabric's surface. The PURL stitch is often used in combination with the knit stitch to create intricate patterns and designs.
