What Is the Extended Half Double Crochet Stitch?

The extended half double crochet stitch (Ehdc) is a variation of the half double crochet that adds an extra yarn-over step. This creates a stitch that is taller than hdc but shorter than double crochet, with better drape and a smoother fabric. The abbreviation is Ehdc.

While similar, the extended half double crochet stitch is slightly shorter than the double crochet but taller than the half double crochet.

Fabric Texture, Drape, and Best Uses

The extended half double crochet stitch creates a fabric that is smooth, slightly open, and more flexible than standard half double crochet.

Because the stitch includes an extra pull-through step, the loops sit a bit taller, allowing the fabric to relax and drape more naturally.

Compared to regular hdc, the extended version feels less dense and less stiff, while still offering more structure than double crochet.

The texture appears gently elongated with subtle vertical definition, making it ideal when you want movement without large gaps.

This stitch works especially well with medium-weight yarns, where the extra height enhances stitch definition without making the fabric feel loose or uneven.

It also pairs beautifully with simple stitch patterns, borders, or colorwork because the fabric remains visually clean.

Best Uses for the Extended Half Double Crochet Stitch

  • Scarves and wraps that need softness and fluid drape
  • Blankets and afghans where flexibility is preferred over stiffness
  • Baby items such as blankets or lightweight garments
  • Garments that require gentle stretch and comfort
  • Projects where half double crochet feels too dense, but double crochet feels too open

If you enjoy the familiarity of half double crochet but want a fabric with more ease and flow, the extended half double crochet stitch is an excellent upgrade.

Common Extended Half Double Crochet Mistakes

  • Stitch looks uneven → tension too tight during the first pull-through
  • Edges too short → use a chain-3 turning chain

Frequently Asked Questions

What is the difference between half double crochet and extended half double crochet?

No. While extended half double crochet is taller than half double crochet, it is still shorter and denser than double crochet. It offers a balance between structure and drape that sits neatly between the two stitches.

Why does my extended half-double crochet fabric look uneven?

Uneven fabric is usually caused by tight tension during the first pull-through.
Try relaxing your grip slightly and keeping your yarn overs consistent throughout each stitch.

Should I use a 2- or 3-chain turning chain?
