How do knitters control the knitting curl? They use a row or two of the purl stitch as the beginning and ending edge of an article or panel. The same thing can be accomplished with the Afghan or Tunisian Crochet Purl Stitch.
Use the purl stitch in your foundation row and the first row or the second and third rows of your project. Just be sure to finish the same way to create a consistent edge.

To work a Purl Stitch:
Note: Hook is always behind the yarn.
1. Cast on – *With yarn in front of hook, insert hook under vertical bar, hold front loop down with your thumb, yo and pull through adding loop to afghan hook; repeat from * across row. Yarn wraps around front of vertical bar.
2. Cast off – *Yo, pull through 2 loops on hook; repeat from * across row.
To Stop Curl:
Make the foundation and first rows using the Purl Stitch. End the panel with two rows of the Purl Stitch. Bind off with a single crochet or slip stitch.
Since it can be a little awkward working a foundation row with the purl stitch, instead cast on using a basic afghan stitch for the foundation row. Then work the next two rows using the purl stitch. Repeat at the end of the item or panel. Bind off with a single crochet or slip stitch.
