How to Half Treble Crochet (UK) / Half Double Crochet (US)

What is the Half Treble or Half Double Crochet Stitch?

The half treble (UK) / half double (US) crochet stitch is the next stitch up from the double crochet (UK) / single crochet (US). It’s half way between the single and the double in US terms and half way between the double and the treble in UK terms.

Confused yet?! The two different terms of crochet can make things really confusing. If you want to check which you’re following or want to make a decision which to follow, I’ve created an easy conversion chart from UK crochet terms to US terms for reference.

What Are the Abbreviations for this Stitch?

In most crochet patterns you will find a list of abbreviations before the pattern begins, telling you which abbreviations refer to which stitches. However, there is a standard that most patterns follow. In UK terms, the half treble is abbreviated with the letters htr and in US terms the half double is referenced as hdc.

Where to Begin the Half Treble / Half Double from a Foundation Chain?

When crocheting the half treble / half double crochet, each row should start with a chain 2. The chain 2 is the turning chain used to bring the yarn up to the correct height for the stitch.

With a foundation chain, make the chain as wide as you would like your project to be, then chain 2 and then begin working back across the foundation chain, starting from the 3rd chain from the hook, missing the last 2 chains you just made. My tutorial on YouTube makes this a lot clearer, if you’re unsure.

How to Begin the Next Row of Half Trebles / Half Doubles

Once you have finished your first row of half trebles / half doubles, turn your work around so the back is facing you. Then you want to begin the next row by chaining 2 again like before, to bring the yarn up to the correct height for the stitch, see the photo below for clarity. Then start your first half treble / half double of this row into the last half treble / half double of the previous row.
