Beautiful Plants For Your Interior
Ever struggled to get that perfect shape in your crochet projects?

The half double crochet decrease (hdc2tog) is your secret weapon to fix these problems, helping you craft fitted, professional-looking pieces with ease. In this guide, we’ll dive into the mechanics of the half double crochet decrease, explore its variations, and show you how to use it to shape your projects like a pro. Whether you’re new to crochet or a seasoned crafter, halfdoublecrochet.com has the tools and resources to spark your creativity.
What Is a Half Double Crochet Decrease?
The half double crochet decrease (abbreviated as hdc2tog or hdc dec) is a technique that combines two half double crochet stitches into one, reducing the stitch count. This method is essential for shaping crochet projects, allowing you to create curves, tapers, or fitted designs. Think snug sweater armholes, rounded hat tops, or smooth amigurumi limbs. If you’re new to the half double crochet stitch, check out our how to half double crochet guide for a quick refresher.
According to crochet experts, the half double crochet is prized for its unique height—taller than a single crochet but shorter than a double crochet—making it ideal for projects needing moderate stretch and structure (The Spruce Crafts). The decrease technique amplifies its versatility, giving you control over your project’s shape.
How to Work a Half Double Crochet Decrease
Let’s break down the standard half double crochet decrease step by step:
- Yarn over (YO), insert your hook into the first stitch, yarn over, and pull up a loop (three loops on hook).
- Yarn over, insert your hook into the next stitch, yarn over, and pull up a loop (five loops on hook).
- Yarn over, pull through all five loops on the hook to complete the hdc2tog.
Done! You’ve reduced two stitches into one. For more detailed tutorials, visit halfdoublecrochet.com or explore our how to do a half double crochet page.
Variations of the Half Double Crochet Decrease
Beyond the standard method, there are variations to suit different project needs:
Lighter Decrease
This variation reduces bulk for a smoother look:
- Yarn over, insert hook into the first stitch, yarn over, and pull up a loop (three loops).
- Insert hook into the next stitch (no yarn over), yarn over, and pull up a loop (four loops).
- Yarn over, pull through all four loops.
This method is great for lightweight projects like shawls or baby garments.
Invisible Decrease
For projects where appearance matters, like amigurumi, try the invisible decrease:
- Yarn over, insert hook into the front loop of the first stitch.
- Insert hook into the front loop of the next stitch (three loops on hook).
- Yarn over, pull through the first two loops.
- Yarn over, pull through the remaining two loops.
This creates a nearly seamless decrease, perfect for crochet kits designed for toys. Want to start an amigurumi project? Our best beginner crochet kit has everything you need.
Using Half Double Crochet Decrease for Shaping
The half double crochet decrease shines in various projects. Here are some key applications:
Shaping Hat Crowns
When crocheting a hat from the brim up, decreases shape the crown. For a hat with 60 stitches, you might work an hdc2tog every 10 stitches to reduce to 54 stitches per round, continuing until the top closes. The half double crochet’s height means fewer rounds are needed compared to single crochet. Find hat patterns in our best crochet kits.
Armhole Shaping for Sweaters
In sweater designs, decreases shape armholes for a snug fit. Place hdc2tog at the start and end of rows to create a smooth curve. A study from Make My Day Creative highlights how decreases adjust bust and waist measurements for tailored results.
Tapering Sleeves
To taper sleeves from shoulder to cuff, work decreases every few rows on both sides. This ensures a fitted look, as seen in our beginners crochet kit patterns.
Amigurumi Shaping
For stuffed toys, decreases create smooth, rounded shapes for heads, bodies, or limbs. Strategic hdc2tog placement prevents gaps, ensuring a polished finish. The invisible decrease is especially effective here.
Tips for Clean Decreases
To make your decreases look professional, keep these tips in mind:
- Maintain Consistent Tension: Pull yarn evenly to avoid loose or tight stitches.
- Tighten Loops: When pulling through all loops, tug gently to close gaps.
- Choose the Right Hook: A 4mm hook works well with medium-weight yarn for balanced results.
- Practice First: Test your half double crochet stitch and decreases on a swatch before starting your project.

Common Mistakes and How to Avoid Them
Even experienced crocheters slip up. Here’s how to dodge common pitfalls:
- Wrong Loop Count: Double-check that you have five loops for the standard decrease.
- Skipping Yarn Overs: Always yarn over before inserting the hook to maintain stitch integrity.
- Misplaced Decreases: Follow your pattern closely to place decreases correctly.
- Inconsistent Tension: Practice matching tension between regular stitches and decreases to prevent warping.
