Hooks and Needles: Simulated Braid Join

I've been stalking Pinterest for a way to join my granny squares together.
   And when I found a picture of the Simulated Braid Join, I knew I had to do it!

Problem was the link didn't work....
   And then when I found it...
   You had to refer to another link to do the first part....
   And then go back to the first link to finish it up...
   Totally a mess!

But I persevered.

First I needed to go to the yarn store...
   To find a great variegated yarn to set off the colors in my square...
   And besides, do you really need an excuse to go to the yarn store?

Pros:
 - Easy-peasy
 - Accentuates the colors in the granny square.
 - Squares up the granny square.

Cons:
 - More yarn used.
 - More time involved.

And you want the low-down on how to do it?  Let me break it down for you:

Step 1:
Edge stitch two blocks by (single crochet, chain three) in each chain-3 space, (single crochet, chain 3, single crochet, chain 3) in each corner.

Step 2:
Hold the two squares right sides together matching up the corners.  Working through both thicknesses, single crochet in the first corner, chain 3 - single crochet - chain 3 across ending with a single crochet in the corner.

Easy peasy, right?
