The triads stitch has an interesting look and is essentially a puff stitch spread over 3 stitches.
If you would like to use the Triad stitch for your own project, you can find the guide on how to use it for any length of foundation chain here

This pattern is written in US terms, but the UK translation is below.
Single crochet (sc) = double crochet
For this square you will need a 3.5 mm hook
Row 1. Sc in 3rd chain from your hook (turning chain counts as a stitch) sc in each stitch across – 30 stitches
Row 2. Chain 1 (doesn’t count as a stitch) make the alternate turning chain in the first stitch.
In the same stitch as the turning chain, yarn over and pull up a loop. In the next stitch yarn over and pull up a loop. In the next stitch yarn over and pull up a loop. This will give you 7 loops on your hook.
Yarn over and pull through 6 loops. Yarn over and pull through the last 2 loops. This is your first triad stitch.
*In the same stitch that you finished the last triad stitch yarn over and pull up a loop, in the next stitch yarn over and pull up a loop. In the next stitch yarn over and pull up a loop. Yarn over and pull through 6 of the loops on your hook. Yarn over and pull through the last 2 loops. Chain 1*
Repeat between *and* dc in the last stitch.
Row 3. Chain 1 (doesn’t count as a stitch) sc in the first stitch and every stitch across – 30 stitches
Rows 4 – 15. Repeat rows 2 and 3 ending on a repeat of row 3
On the top and bottom edges, make a sc in each stitch.
On the sides make 2sc in the side of row 1, then 1 sc in the side of every sc row, and 3 sc in the side of every triad row.
