The foundation half double crochet stitch is a great way to start crochet projects when crocheting half double crochet stitches.

This stitch creates a chain stitch and a half double crochet in the same stitch, which is why it is often referred to as the chainless foundation half double crochet or the half double crochet foundation chain.

The steps for this stitch are quite simple, and once you understand the basics, it is easy to crochet. So let’s dive into this foundation half double crochet tutorial to learn a new technique.

What is the Foundation Half Double Crochet

The foundation half double crochet is one of the foundation crochet stitches.

Crocheters often come across it when starting crochet projects, where the chains and half double crochet stitches are worked at the same time as the first row of stitches.

This is a great way to get a more stretchy foundation row, compared to crocheting the foundation chains first, then working the half double crochet row separately.

The stretchy edge you get is great in many instances, such as when crocheting the neckline on raglan garments and yoke sweaters, tops and cardigans. But it is also great for anything where you want a stretchy fabric.

Another bonus is the fact that it can make the edge more even and easier to block a new crochet project like blankets and other new patterns you follow.

The steps of the Foundation Half Double Crochet Stitch:

  1. Chain 3.
  2. Yarn over. Insert hook into 3rd chain from hook, pull up a loop. Yarn over and pull through first loop (making the chain). Yarn over and pull through the 3 loops on the crochet hook.
  3. Yarn over. Insert hook into previous chain you made*, pull up a loop, yarn over and pull through first loop (making the chain). Yarn over and pull through the 3 loops on the crochet hook.
  4. Repeat step 3 until you’ve made enough stitches**.

*It should look like you go through a resemblance of a normal stitch, with 2 strands of yarn.

*3rd chain in step 1 makes 1 stitch, step 2 makes 1 stitch & every time step 3 is repeated you make 1 stitch.

Materials Needed

To crochet the foundation half double crochet you can use any crochet hook size and yarn. If you’re following a crochet pattern, use the crochet hook and yarn suggested.
