If you know how to do a single crochet then you can do any basic crochet stitch. The double crochet is done the same way as the single with an extra yarn over. The treble crochet is done the same way as the double crochet with an extra yarn over. And so on for any taller crochet stitches you’d like to do.
Below I’ll show you the steps for doing a double treble crochet as well as the info to keep adding yarn-overs to make the triple treble, quadruple treble and quintuple treble crochet stitches.
How to Crochet Double Treble Crochet Stitch (DTR)
Step One: Yarn over the crochet hook three times.
Insert the crochet hook into the work where you want the stitch. If you are making the first double treble into your starting chain then insert the crochet hook into the sixth stitch; the first five stitches in the chain count as the first double treble stitch.
Yarn over and pull through the stitch, leaving five loops on the hook.
Yarn over and pull through the first two loops, leaving four loops on the hook.
Yarn over and pull through the first two loops, leaving three loops on the hook.
Yarn over and pull through the first two loops, leaving two loops on the hook.
Yarn over and pull through the remaining two loops.
That’s your double treble crochet stitch. Repeat steps 1-7 across the row for a full row of double treble crochet stitches. If you want to create another row of these stitches then chain five (which counts as the first double treble) and turn your work and repeat steps 1-7.
Triple Treble (TrTr), Quadruple Treble (Quad Tr) and Quintuple Treble (Quin Tr) Crochet Stitches
For each of these stitches, simply add one more yarn over to the size of the one before it and proceed as usual:
For the quintuple crochet stitch, start with yarn over 6
As you can tell, you always start with one yarn over more than the number of stitches you want for the height of the stitch. So theoretically if you wanted to create crochet stitches than were 9 stitches tall then you would start with a yarn over of 10.
