What is Half Double Crochet?

Half Double Crochet (HDC) is a foundational crochet stitch that sits between the single crochet (SC) and double crochet (DC) in height. It produces a fabric that’s denser than DC but more flexible than SC, making it ideal for projects like scarves, hats, blankets, and clothing.

In U.S. crochet terminology, it’s called Half Double Crochet, while in the U.K., it’s known as half treble crochet. Regardless of the name, the technique is the same: a series of yarn overs and loops create a stitch with a distinctive third loop, which can be used for unique textures and patterns.

For beginners, mastering HDC is a critical step after learning chain stitches and single crochet. It builds on foundational skills and paves the way for more complex stitches and patterns. To learn more, visit our What is Half Double Crochet page.

How to Work a Half Double Crochet

Learning Half Double Crochet is straightforward once you’ve grasped the basics. Here’s a step-by-step guide:

1. Create a Foundation Chain:
   • Crochet a chain of your desired length. For practice, try a chain of 10-15 stitches.
2. Yarn Over (YO):
   • Wrap the yarn over the hook from back to front.
3. Insert Hook:
   • Insert the hook into the third chain from the hook (in some patterns, the skipped chains count as the first HDC).
4. Yarn Over and Pull Up a Loop:
   • Yarn over again and pull through the chain, creating three loops on the hook.
5. Yarn Over and Pull Through All Three Loops:
   • Yarn over once more and pull through all three loops on the hook to complete one HDC.
6. Repeat:
   • Continue across the row: yarn over, insert into the next stitch, yarn over and pull up a loop (three loops), yarn over and pull through all three loops.
7. Turning Chain:
   • At the end of the row, chain two (turning chain), turn your work, and begin the next row by inserting the hook into the first stitch (or as pattern instructs).

Note that some patterns count the turning chain as a stitch, while others do not. Always check your pattern instructions for clarity.

Applications of Half Double Crochet

Half Double Crochet’s versatility makes it suitable for a wide range of projects. Its balanced height and texture offer both functionality and aesthetic appeal. Common applications include:

• Scarves and Shawls: HDC creates warm, dense fabric perfect for winter accessories.
• Hats and Beanies: Its elasticity makes it ideal for comfortable headwear.
• Blankets and Throws: HDC offers warmth and breathability, perfect for cozy blankets.
• Clothing: From sweaters to cardigans, HDC crafts stylish, comfortable garments.
• Home Decor: Think pillows, rugs, and coasters, where HDC’s durability and softness shine.

HDC is often combined with other stitches to create intricate patterns and designs. Its moderate height makes it a favorite for designers. To explore patterns and projects using HDC, check out our Crochet Kits page for everything you need to start your next project.

Advanced Half Double Crochet Techniques

Once you’ve mastered basic HDC, try these advanced techniques to elevate your skills and create more intricate designs:

Increasing and Decreasing

• Increasing: Work two HDC stitches into the same stitch to add stitches to a row.
• Decreasing: Use HDC2TOG (Half Double Crochet Two Together) to combine two stitches into one. See our Half Double Crochet Decrease tutorial for details.

Working in Different Loops

• Back Loop Only (BLO): Crocheting in the back loop creates a ribbed, knit-like texture.
• Front Loop Only (FLO): Working in the front loop produces a different texture, often used for specific patterns.
• Third Loop: The third loop unique to HDC can be used for textured stitches like the camel stitch. Learn more at our Foundation Half Double Crochet page.

Color Changes

• Learn to seamlessly switch colors in HDC to create vibrant patterns and designs.

Textured Stitches

• Combine HDC with popcorn, puff, or bobble stitches for added dimension. For example, the Herringbone Half Double Crochet adds a unique twist to traditional HDC.

These advanced techniques allow you to take your crochet projects to the next level, creating stunning, professional-quality pieces.

Foundation Half Double Crochet

The Foundation Half Double Crochet (FHDC) is a technique that combines creating a foundation chain and the first row of HDC simultaneously, ideal for projects needing a stretchy edge, like hats or garments.

Steps:

1. Make a slip knot on the hook.
2. Chain two.
3. Yarn over and insert the hook into the first chain (closest to the slip knot).
4. Yarn over, pull up a loop (three loops on the hook).
5. Yarn over, pull through one loop (forming the “chain” part).
6. Yarn over, pull through all three loops (completing the HDC).
7. For the next stitch, yarn over, insert into the “chain” part of the previous stitch, and repeat steps 4-6.

This technique can be tricky at first but becomes a valuable skill with practice. Visit our Foundation Half Double Crochet page for a detailed tutorial.

Herringbone Half Double Crochet

The Herringbone Half Double Crochet is a variation that creates a slanted, herringbone-like texture by slightly modifying the standard HDC technique.

Steps:

1. Yarn over, insert into the next stitch.
2. Yarn over, pull through the stitch and the first loop on the hook (similar to a slip stitch).
3. Yarn over again, pull through the remaining two loops.

This stitch adds visual interest and can be used in place of regular HDC. Learn more at our Herringbone Half Double Crochet page.

Troubleshooting Common Half Double Crochet Issues

Even experienced crocheters encounter challenges with HDC. Here are common issues and solutions:

1. Uneven Edges:
   • Likely caused by inconsistent turning chains or miscounted stitches. Count your stitches at the end of each row and ensure proper turning chain placement.
2. Stitches Too Tight or Too Loose:
   • Tension is key. For tight stitches, try a larger hook or relax your grip. For loose stitches, use a smaller hook or tighten your tension.
3. Difficulty Identifying Stitches:
   • Beginners may struggle to see where to insert the hook. Use light-colored yarn and good lighting to make stitches clearer. Practice with a larger hook and yarn for visibility.
4. Fabric Curling:
   • This may result from incorrect tension or mismatched hook and yarn sizes. Adjust your hook size or block your work after completion.
