This tutorial uses US terminology and refers to the stitch as the Back Loop Herringbone Half Double Crochet (BLHHdc).

In UK terminology, this stitch is called the Back Loop Herringbone Half Treble Crochet (BLHHtr).

About the Stitch

The basic Herringbone Half Double Crochet is a beautifully textured stitch that creates a subtle angled effect. It produces a denser, less gappy fabric compared to a traditional half double crochet, giving your work a lovely, polished finish.

It is simple to work, and once you’ve practised it a few times, it develops a smooth, natural rhythm.

When worked into the back loop only, it adds an entirely new dimension. The stitch forms a defined ribbed texture with wonderful depth and structure — a look I love for pieces that need both stretch and visual interest. I have several new designs with this stitch coming very soon!. Subscribe to the webpage for notifications on launch days!

Back Loop Herringbone Half Double Crochet (BLHHdc)

This stitch can be worked starting from a base row of either single crochet or half double crochet. Simply create your starting chain, work the chosen stitches across, and begin the BLHHdc on the next row. Alternatively, you can start with a foundation row of single crochet or half double crochet and work the BLHHdc into the back loop only of the following row. I personally prefer a foundation single crochet row, as it gives a neat edge with excellent stretch.

Step 1: Yarn over, insert hook into the back loop only of the next stitch

Step 2: Pull up a loop. 3 loops on the hook.

Step 3: Draw the first loop through the second loop. 2 loops remaining on the hook.

Step 4: Yarn over and pull through the remaining 2 loops on the hook.

One BLHHdc complete.

Repeat across as instructed in your pattern.
