If you’re expanding your crochet skills, learning how to half double crochet two together (abbreviated as hdc2tog) is a great next step. This technique is a form of decreasing, which means you’re turning two stitches into one. It’s especially useful for shaping crochet projects—like narrowing a hat, forming armholes in a sweater, or tapering a scarf.
In this guide, you’ll learn exactly what half double crochet two together means, when to use it, and how to do it step by step.
What Does Half Double Crochet Two Together Mean?
The half double crochet two together (hdc2tog) is a method that combines two half double crochet stitches into one. This helps reduce the number of stitches in your row or round, which is necessary for shaping your project.
Unlike regular half double crochet (hdc), where you work into one stitch, hdc2tog uses two stitches to make one new stitch. It’s easy to learn and just takes a few extra steps.
When to Use HDC2TOG
You might need to use half double crochet two together in the following situations:
- Shaping garments, like sleeves, armholes, or necklines
- Tapering hats, especially at the crown
- Creating curves or angles in accessories like shawls or bags
- Working amigurumi where specific shaping is needed
If a pattern tells you to decrease, and you’re working in half double crochet, hdc2tog is likely what it wants.
How to Half Double Crochet Two Together
Here’s a simple step-by-step guide to help you practice hdc2tog:
Step-by-Step Instructions:
- Yarn over Just like you would in a normal half double crochet stitch.
- Insert hook into the next stitch Go through the front and back loops as usual.
- Yarn over and pull up a loop Now you have three loops on your hook.
- Yarn over again
- Insert hook into the next stitch Now we’re moving into the second stitch to join them together.
- Yarn over and pull up another loop You now have five loops on your hook.
- Yarn over and pull through all five loops This completes your half double crochet two together. You’ve successfully turned two stitches into one.
A Quick Visual Description
If you’re used to reading crochet stitches by look:
- A normal hdc has one top loop and a wide “V” on the front.
A hdc2tog has a slightly tighter top and sits a little shorter, but blends in well with surrounding hdc stitches.
It doesn’t leave a big gap like some decrease stitches might, making it a clean and seamless option for shaping.
Practice Row for HDC2TOG
To practice the stitch, try this short sample row:
- Chain 14
- Work one row of half double crochet across
- On the next row, alternate:
- 1 hdc in first stitch
- hdc2tog over next two stitches
- Repeat across the row
You’ll notice your fabric starts to narrow—that’s your half double crochet two together doing its job.
Helpful Tips
- Don’t skip stitches by accident: It’s easy to overlook the stitch after a decrease, so count your stitches as you go.
- Mark your decreases: If you’re shaping something symmetrically, use stitch markers to ensure your hdc2tog stitches are lined up on both sides.
- Work loosely: Pulling your loops too tight can make it hard to work into the next round or row.
When Not to Use HDC2TOG
While the half double crochet two together is very useful, it might not be ideal if you need a very smooth curve or if you’re working with open lacy stitches. In those cases, a different decrease method (like sc2tog or dc2tog) might fit better with your fabric.
Final Thoughts
Mastering the half double crochet two together technique opens the door to more advanced crochet projects. It’s a basic but powerful way to shape your work and achieve cleaner designs. Whether you’re making hats, cardigans, or sculpted toys, knowing how to decrease with hdc2tog gives you the control and flexibility to crochet with confidence.
