Double Treble Crochet

Even though this is one singular complete stitch like the basic stitches, the double treble crochet stitch is considered a special stitch because it is rarely used in crochet. It is not common like the basic stitches are. The double treble crochet is a stitch that is one step taller than a treble crochet.

Yarn over the hook 3 times, insert the hook in the stitch (a), yarn over, draw the loop through (b), [yarn over, draw through 2 loops on the hook] 4 times (c, d, e, f).
