Rows 1 and 3: Purl 1, *Knit 2, Purl 1*
Row 2: Knit 1, *Purl 2, Knit 1*
Row 4: Knit all stitches
Repeat these four rows for pattern.
Don't forget to look at the back of your knitting. What is deemed as the 'wrong' side may be just as nice as the 'right' side of the fabric. For instance, the back of Waffle Stitch looks like Knit 1, Purl 3 ribbing. While it really isn't technically ribbing, it still looks pretty!
