How to Decrease Half Double Crochet hdc2tog Tutorial

Sharing is caring!

Learn how to half double crochet two together, also known as the hdc2tog. This step by step tutorial will help you learn how to decrease the number of stitches you have when working the hdc stitch.

This stitch decrease abbreviates as hdc2tog in written crochet patterns. I actually show you two different ways to do this stitch here.

First I start with the a regular hdc2tog decrease, which gives you 5 loops to finish with. However, I often use the modified version I show you second.

It’s a little less bulky and still looks similar to a regular hdc stitch. It ends with only 4 loop. This is one of those decrease techniques that I wish I knew sooner!

Free Patterns Using the HDC2TOG

The Ana Hat is a bottom up crochet hat that uses decreases to close up the top.

The Autumn Crunch Hat is a lightly textured beanie that uses basic crochet stitches and the hdc decrease to close up the top.

To see it in action on a non hat pattern, the Bryce Canyon Kids Cardigan uses this hdc stitches and decreases to shape the neckline, as does the Briones a women’s sweater.

These kids cardigans are worked with basic stitches and the half double crochet decrease stitch to shape the v-neck.

The single crochet decrease is an essential when reducing a single stitch.

The invisible decrease is a beautiful way to make decreases without it being so obvious (hence the name)!

The double crochet decrease can be useful and is actually a beautiful crochet stitch when worked as a dc3tog like in the Mid Summer Cardigan.

Both version of hdc2tog side by side.
Here the two versions of the hdc2tog side by side (3rd + 2nd stitches from the last stitch of the row).

The above photo shows a regular hdc at the end of the row, with the decrease before it. Usually you leave the first hdc of the row, and start decreases in the second stitch of the row.


  1. You”ll need to start with at least one row of stitches to be able to decrease.
  2. Many hdc patterns start with a chain 2 and count this as the first stitch of the row. I do not write my hdc patterns this way, as I find it too loose and open. I prefer a ch 1 at the beginning of a row of hdc, which does not count as a stitch.

How to Get Started

  1. To start a row of half double crochet stitches begin with any number of chains, plus 2.
  2. Hdc in the 2nd chain from hook and in each chain across.
  3. Turn your work at the end of a row.
  4. Ch 2 to start a new row.
