The crocheted Tunisian purl stitch (also known as purl stitch) is a common variation of basic Afghan stitch. Tunisian purl stitch looks like rows of rounded bumps. As with any kind of Afghan stitch, you begin Tunisian purl with a foundation row made of basic Afghan stitch.
Chain 16 stitches for your foundation chain.
Because Afghan stitches require you to pull loops up through existing stitches, you need to start with a foundation row.
To work the first half of the foundation row, insert the hook in the second chain (ch) from the hook.
Begin counting stitches from the stitch directly below the loop on your hook.
Yarn over (yo) the hook and draw your yarn through the chain stitch.
You should have two loops on your hook.
Insert your hook in the next chain and repeat the preceding step in each chain across the foundation chain.
Your hook is now loaded up with loops. This is known as drawing up the loops. You should have 16 loops — one for each chain stitch in your foundation chain. The first half of your foundation row of basic Afghan stitch is complete.
To work the second half of the foundation row, yarn over (yo) the hook and draw your yarn through 1 loop on the hook.
Work with only one loop in this step.
Yarn over the hook and draw your yarn through the next 2 loops on the hook.
Repeat this step across the row until 1 loop remains on the hook. Your foundation row of basic Afghan stitch is complete. (This single loop on your hook will become the first stitch of the next row.)
Begin the first half-row of Tunisian purl stitch: With the index finger of your yarn hand, bring the working yarn to the front of your work; insert your hook under the next vertical stitch.
Keep your hook behind the strand of working yarn.
Yarn over (yo) and draw the yarn through the stitch.
Repeat the preceding step and this step across the row until you reach the next-to-last stitch.
Insert your hook under the last 2 vertical bars at the end of the row.
Be sure to get your hook through both bars.
Yarn over and draw the yarn through the stitch.
You should have 16 loops on your hook.
To work the second half of the row, yarn over (yo) the hook and draw your yarn through 1 loop on the hook.
Be sure to work with only one loop.
Yarn over the hook and draw your yarn through the next 2 loops on the hook.
Repeat this step across the row until 1 loop remains on the hook.
