What is a Half Double Crochet?

The half double crochet stitch (hdc) is a mid-height stitch that’s taller than a single crochet but shorter than a double crochet. It’s unique because it creates a smooth, dense texture with a subtle ridge when worked in rows.

This stitch is ideal for:

Garments like sweaters and cardigans.
Blankets with a soft, cohesive texture.
Accessories such as hats, scarves, and bags.

The hdc is versatile enough for both beginners and experienced crocheters, making it a staple in many crochet patterns.

How to Half Double Crochet, Step-by-Step

Here’s how to work the hdc stitch:

Create a Foundation Chain: Start with a chain (ch) of your desired length. For practice, chain 12.
Yarn Over (yo): Wrap the yarn over your hook from back to front.
Insert Your Hook: Skip the first two chains from your hook (these count as the turning chain). Insert your hook into the third chain.
Yarn Over and Pull Through: Yarn over again and pull the yarn through the chain. You should now have three loops on your hook.
Complete the Stitch: Yarn over once more and pull through all three loops on your hook. You’ve completed one hdc stitch!
Repeat Across the Row: Continue working one hdc into each chain across the row. When you reach the end, chain two (this counts as your turning chain) and turn your work.

Pro Tip: Make sure your turning chain is the correct height to maintain an even edge.

Working Half Double Crochet in Rows

When working hdc in rows, you’ll notice a subtle ridge forms on one side of your fabric. This is created by the top loops of the stitch and adds texture to your project.

Tips for Neat Rows:

Always count your stitches at the end of each row to ensure consistency.
Use a stitch marker to mark the first stitch of each row to avoid confusion.
Keep your tension even to create a uniform fabric.

How to Half Double Crochet in Rounds

The hdc stitch works beautifully in rounds, making it a popular choice for hats, baskets, and circular blankets. Here’s how to do it:

Start with a Foundation: Use a magic ring or chain two and work your stitches into the second chain from the hook.
Work Your Stitches: Yarn over and insert your hook into the designated space. Yarn over again, pull through, and complete the hdc as usual.
Join the Round: At the end of each round, join the last stitch to the first with a slip stitch. Alternatively, work in a continuous spiral for a seamless look.

Pro Tip: Use a stitch marker to track the beginning of each round when working in spirals.

Tips for Perfect Half Double Crochets

Mind Your Turning Chain: The turning chain in hdc is typically two chains. Make sure to count it as a stitch if the pattern specifies.
Practice Tension Control: Uneven tension can make your stitches look messy. Practice to achieve consistent tension.
Use the Right Hook Size: Check your yarn label for the recommended hook size to ensure your stitches are proportional.
Count Your Stitches: Counting at the end of each row or round prevents accidental increases or decreases.
