Stockinette stitch is a popular knitting technique that creates a smooth, flat fabric. It is made by alternating rows of knit stitches and purl stitches. The front side, known as the "right side," features a series of V-shaped stitches, while the back side, or "wrong side," shows a bumpy texture. This stitch is commonly used in various knitting projects, including garments and accessories. While it produces a beautiful finish, stockinette stitch can curl at the edges, so knitters often use borders or other stitches to help maintain the shape of their work.
