The Double Crochet Joining Stitch
I love this stitch for connecting granny squares. It makes a great border, does a great job of linking all the squares together and is easy to do. One great idea: Use it to join sweater arms to the body of your sweater. It will give you a super flexible joint and will look very old school and yet futuristic.
The double crochet joining stitch is a double crochet (dc) stitch that is worked in two directions so that you can join two pieces. To start this stitch, slip stitch with your color in the corner space of the granny square. Chain 2.
The chain 2 will act as your first double crochet. Now yarn over and grab your other piece. In this example I will have both pieces laying on the same side, but you can do it either way depending on the pattern your following and the look you're going for.
After you yarn over, insert your hook in the corner space of the other granny square, pull up a loop and complete a double crochet stitch.
This completes your first connection! For each subsequant chain you will add a double crochet to the next chain of the first square, then do the same with the next chain of the other square.
Here's a picture of your next Double crochet, notice that it's on the bottom. You'll need to keep alternating, bottom then top, bottom then top. Don't skip stitches as it'll make your piece pucker.
Adding a dc to the top square
Ok, I think you get the idea. Keep going!
I made a huge Queen sized granny square blanket using this connection technique and I still love it. I used squares of different colors and adding the double crochet joining stitch in blank which made the color pop even more.
