Half Double Crochet: step-by-step tutorial

Half double crochet sits between single and double crochet in height. Yarn over, insert the hook into the stitch, yarn over and pull up a loop so three loops sit on the hook. Yarn over once more and pull through all three loops. The result is a quick, warm fabric.

How do you do a half double crochet stitch?

A half double crochet is made by yarning over, inserting the hook, pulling up a loop, then pulling one yarn-over through all three loops at once.

The single pull-through of three loops is what makes hdc faster than double crochet and taller than single crochet.

What is the third loop in half double crochet?

The third loop is a horizontal bar that sits just below the top V on the back of each half double crochet row. Working into it pushes the V forward and creates a knit-look rib.

Third-loop hdc is a popular choice for hat brims, sweaters and blankets that should look knitted.

Does the chain 2 count as a stitch in half double crochet?

It depends on the pattern. Many modern patterns treat the ch 2 as not counting and place the first hdc in the first stitch, which keeps edges straighter.

Older patterns often count the ch 2 as the first hdc and skip the first stitch. Follow the pattern notes and count stitches to confirm.
