Tunisian crochet is a unique craft, a hybrid of knitting and crocheting. You use your Tunisian crochet hooks to make loops like crochet but like knitting, you keep the stitches on the hook for the foundation row and then work them over in the next row. Tunisian Double Crochet (TDC) stitch is a variation of the basic Tunisian crochet stitch, also known as the Afghan stitch. It creates a taller and more open fabric compared to other traditional Tunisian crochet stitches.

When you’ve mastered the basic Tunisian crochet stitches such as Tunisian Knit Stitch and Tunisian Simple Stitch and The Tunisian Purl Stitch, you can easily explore this unique stitch pattern. The stitch pattern works in a unique way, where you lay the foundation row by picking up stitches on your crochet hooks and then working them over the next row. You work a row twice. The interchangeable Tunisian crochet hooks play an important role in the craft as it offers the desired length to accommodate stitches on the hook before working them off. The interchangeable cords are simply the ones you use in your knitting needles. So, if you are a well-versed knitter you already have the versatility of the cords to work on varying lengths and circumferences of projects. And, if you’ve never tried you have the perfect opportunity to try.

What you’ll need to know before working on Tunisian Double Crochet Stitch

Tunisian Double Crochet stitch is a versatile and attractive stitch that adds texture to your projects. Whether you're making scarves, blankets, or garments, mastering this stitch opens up a world of possibilities for your crochet creations. This one is quite different than the basic crochet stitch of double crochet stitch, abbreviated as DC.

Tension and Hook Size:

Like with any crochet stitch, tension is essential. Make sure your tension is consistent to achieve an even fabric.

You might need to use a larger hook size than you would for regular crochet to maintain the same gauge, as Tunisian crochet tends to be tighter.

Tunisian Double Crochet Fabric Characteristics:

Tunisian Double Crochet creates a fabric with a nice drape and a more open texture compared to other Tunisian stitches like Tunisian Simple Stitch or Tunisian Knit Stitch.

The fabric may be thicker than regular double crochet fabric due to the nature of Tunisian crochet, where you have multiple loops on the hook for each stitch.

Here's everything you need to know about the Tunisian Double Crochet (TDC) stitch:

Step 1:  Basic Tunisian Crochet Foundation:

Before working TDC, you should be familiar with the basic Tunisian crochet foundation, which involves creating a foundation chain and picking up loops from it using a Tunisian crochet hook.

Step 2: Starting a Row (Forward Pass):

To start a row of TDC, you'll first need to complete the foundation chain.

Insert the hook from right to left into the second chain from the hook, yarn over, and pull up a loop. Continue this across the entire row until you have a loop on the hook for each chain stitch in the foundation.

Step 3: First Row (Return Pass):

The Return Pass is the same for all Tunisian crochet stitches. Yarn over and pull through one loop on the hook (this is the edge stitch). Then, yarn over again and pull through two loops on the hook. Repeat the "yarn over, pull through two loops" until only one loop remains on the hook.

Step 4: Working the TDC Stitch:

For the TDC stitch, yarn over and pull through two loops on the hook, leaving two loops on the hook.

Yarn over again and pull through the next two loops on the hook, leaving two loops on the hook.

Repeat the "yarn over, pull through two loops" until only one loop remains on the hook.

Step 5: Forward and Return Pass (Rows 2 and beyond):

For the next row and all subsequent rows, repeat steps 3 and 4.

Insert the hook from right to left under the next vertical bar (the vertical strand of yarn between two loops) and repeat the TDC process until the end of the row.

Work the Return Pass as discussed above.

Combining TDC with Other Stitches:

Tunisian crochet offers various stitch patterns and textures. You can combine TDC with other Tunisian stitches or use it in combination with regular crochet stitches to create unique designs.
