Seed stitch is a simple knitting technique that creates a textured pattern. It alternates between knit and purl stitches, resulting in a bumpy, visually appealing fabric. This stitch can be used for various projects, including scarves, blankets, and hats. To work seed stitch, you knit one stitch, then purl the next, repeating this pattern across the row. On the following row, you switch the order, purling where you knit and knitting where you purled. This back-and-forth method gives the fabric its characteristic look and feel, making it a popular choice among knitters.
