The Treble V-Stitch Decrease is one stitch that bridges the gap over several, and when crossed over additional Treble V-Stitch Decreases appears to create a unique braided effect. You are working this “braid” from the side, creating a “forward” and “backward” arm that set up the effect.
To begin you need to have a few rows of worked fabric, this works best on single crochet stitches as the stitches are short, and relatively square in shape, allowing for even placement of the Treble V-Stitch Decrease.
Yarn over twice, as for a treble crochet, and insert the hook around the 2nd stitch to the right, 3 rows below as for a front post stitch, yarn over and pull through a loop. This create an “arm” that is “behind” or is working the opposite direction from the direction you are working in the row.
Yarn over and pull through 2 loops, twice. Leaving remaining 2 loops on the hook.
Yarn over twice, insert hook around the 5th stitch to the left, three rows below. This will be in the same row as the other “arm”, but six stitches apart. Yarn over, pull through a loop.
Yarn over and pull through 2 loops, twice. Yarn over and pull through the last 3 stitches.
When multiple of these stitches are worked together, they will overlap, creating a braided effect.
