How To Do The Tunisian Half-Double Crochet Stitch

Today we are learning all about the Tunisian Half-Double Crochet Stitch (THDCS)! I really love the look and texture of this stitch! Pay close attention though, this stitch starts out differently than we have been doing. The foundation row is what gets you started!
Foundation Row
To work the THDCS, you will work a “modified” foundation row by yarning over before inserting your hook into each chain and pulling up a loop. This will result in a lot of loops on your hook, so make sure you give yourself enough room! You will then chain 1 for the return and instead of pulling thru just 2 loops, you’re going to yo, pull thru 3 loops–like a waltz. Pull thru 3 loops all the way until you only have 1 loop left on your hook.
Regular Rows
To work the next rows, you can ch1 at the beginning (also something we don’t normally do!) or you can omit that to keep the right edge a little tighter, the choice is yours. *Yo, insert hook behind the next vertical bar and the next bar that appears to be leaning away from it, yo and pull up a loop; rep from * until you reach the edge stitch: yo, insert into 2 loops of the left edge stitch, yo, pull up a loop.
The return pass is to chain 1, yo, pull thru 3 loops all the way down!

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.

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 foundation row per the instructions above.
Row 1, Forward Pass: Crochet a row of THDCS (see above), end with yo, insert into edge stitch, pull up a loop.
Row 1, Return Pass: Ch1, yo, pull thru 3 loops until you have only 1 loop left.
Row 2 and onward: Complete the instructions for row 1 both forward and return passes.
