How To Do The Tunisian Double Crochet Stitch

Let’s learn how to do the Tunisian Double Crochet Stitch (TDCS). Last time, we learned all about the THDCS and it was a little different than we’re used to. The TDCS goes back to the normal way of working a normal foundation row first, then getting into the stitch for the next row.
Working the stitch
To work the Tunisian Double Crochet Stitch (TDCS), yo, insert hook in the front bar, pull up a loop, yo and pull thru two loops on the hook. Repeat with each stitch across. To adjust for height, add a chain to both the left and right edges of the fabric.
There are a couple of ways to work the left edge stitch, one of which, I prefer even though it is not considered the “correct way” to work this stitch.
Option 1: work a left edge stitch as “normal” by not yarning over, inserting your hook into the two loops, yo pull up a loop; then ch1 to get ready for your return pass, but also chain 1 again to get it up to height. So… work a normal edge stitch but ch2 before doing the return pass.
Option 2: Yo, insert into edge stitch, yo pull up a loop, yo and pull thru two loops. When you get ready to do your return pass, ch1. I prefer Option 2 simply because it does not create a “gappy” side.

I used:
Worsted/Aran/#4 weight yarn–Brava Worsted by Knit Picks in Cornflower, Tidepool, Alfalfa, and mint. I was able to get 2 squares out of each skein. As there are 12 squares, if you are using the same yarn, you will need 3 of each. I also used Brava Worsted Speckle in Tidal for borders and joining.

Machine was and dry
I used a 6.5mm Tunisian hook from Furls and also one from Love To Crochet–a set I bought on Amazon.
Written Instructions
To work this swatch with me, I recommend doing at least 4″ x 4″ square to learn the stitch before doing a pattern. For the CAL, you will need to do this for 12″ x 12″ square. This stitch does not have a multiple, you can simply crochet any number of stitches until you reach the desired measurement.
Complete a normal foundation row–you can find instructions for this in the Introduction to Tunisian post, here.
Row 1, Forward Pass: Crochet a row of TDCS, working an edge stitch with either option 1 or 2.
Row 1, Return Pass: Complete a normal return pass (see the introduction post, here)
Row 2 and onward: Complete the instructions for row 1 both forward and return passes.
