Crocheting a half double crochet blanket block is a great way to create a customizable, cozy project. This Half Double Crochet (HDC) blanket block is simple yet effective, making it a perfect addition to any crochet blanket. In this guide, we’ll go over the materials you need, step-by-step instructions, and helpful tips to ensure your block turns out beautifully.


How to Do a Half Double Crochet (HDC) Stitch

The half double crochet (HDC) stitch is a versatile and slightly taller stitch than a single crochet, but shorter than a double crochet. It creates a soft yet firm texture, making it perfect for blankets, scarves, and other cozy projects.

Step-by-Step Instructions

  1. Start with a Foundation Chain:
    • Begin by chaining the number of stitches required for your project.
  2. Yarn Over (YO):
    • Wrap the yarn over your hook before inserting it into the stitch.
  3. Insert Hook:
    • Insert your hook into the next stitch (or the third chain from the hook if working from a foundation chain).
  4. Yarn Over and Pull Through:
    • Wrap the yarn over your hook again and pull it through the stitch. You should now have three loops on your hook.
  5. Yarn Over and Pull Through All Loops:
    • Wrap the yarn over again and pull through all three loops on your hook. You have now completed one half double crochet stitch!
  6. Repeat:
    • Continue repeating steps 2-5 for each stitch across the row.
  7. Turning for the Next Row:
    • At the end of the row, chain two (this acts as the first HDC of the next row) and turn your work.

Tips for Perfect Half Double Crochet Stitches

  • Maintain Even Tension: Keep your yarn tension consistent for uniform stitches.
  • Count Your Stitches: Always count your stitches to ensure you don’t accidentally increase or decrease the number.
  • Practice with Swatches: If you’re new to HDC, practice making small swatches before starting a full project.

Step-by-Step Instructions For Half Double Crochet Blanket Block

Foundation: Chain 25.

  1. Row 1: Start in the 3rd chain from the hook (the initial chain 2 counts as the first HDC). Work 23 HDC stitches, chain 2, and turn. (Total stitches: 24)
  2. Rows 2-13: Work 24 single crochet (SC) stitches in each row, chaining 1 and turning after each row. (Total stitches: 24 per row)
  3. Measure Your Block: By the end of Row 2, your block should be approximately 6 inches wide. If it’s too small, restart with an additional stitch; if it’s too wide, reduce the number of stitches. A ¼-inch variance is acceptable.
  4. Edging: At the end of your final row, chain 1 and single crochet evenly down the side of the block (aim for about 26 SC stitches). In the last stitch, SC 3 into the corner and turn.
  5. Bottom Edge: Continue to SC across the bottom of the block, placing 3 SC stitches in the opposite corner before turning.
  6. Side and Final Edge: SC evenly along the remaining side (again, aim for approximately 26 stitches). SC 2 in the final corner and stop.
  7. Final Measurement: Your half double crochet blanket block should now measure about 7 inches. If needed, SC around all four sides once more to reach the correct size.
  8. Finish Off: Use a yarn needle to weave in the tail.

Helpful Tips for Success

  • Consistent Tension: Make sure your stitches are even to maintain uniformity across all blocks.
  • Measuring Accuracy: Measuring after Row 2 ensures you are on track with sizing early on.
  • Hook Size Adjustment: If crocheting along the edges feels too tight, consider switching to a smaller hook (4mm or 4.5mm) but stay consistent for all blocks.
  • Row Counting: A row counter can help keep track of your progress and ensure accuracy.
