Ribbing is a border that is commonly used on the cuffs of sweaters. It is used because it produces a stretchy fabric. It is made with a combination of knit stitches and purl stitches. Ribbing can be done with any number of stitchs, but two or three is common. In our example, we use two.
Knit two stitches. Bring the yarn from the back of your work between the needles to the front. Now purl two stitches. Bring the yarn to the back of your work between the needles. Knit two stitches. Continue to knit two stitches, purl two stitches until you reach the end of the row or until the pattern instructs you to do something different.
On subsequent rows, knit the knit stitches (V stitches) and purl the purl stitches (bump stitches) Remember to have the working yarn in BACK when you knit and in FRONT when you purl.
