This is another way of sewing motifs together and it's a favourite joining method of mine. Partly because it's so invisible, but also because I just love the way the corners pull in together so neatly and the squares butt so closely up next to each other.
I've made this tutorial an 'Improver' tutorial as it is a little bit tricky to get going with and possibly not as fast as some of the other joining methods. But for me, the end look of the squares is well worth a little extra time.
If you'd like more help with making the square motif, please have a look at my Classic Granny Square tutorial.
PART ONE: JOINING THE FIRST SQUARES
The needle will go in through the top of the first corner chain (between the two loops or 'v') and then out through the top of the second corner chain.
Then bring bring the needle out of the top of the next stitch. (Come up under the back loop from behind.)
(Don't leave it too long or it gets to hard to pull the yarn tight and you get left with baggier bits of even the yarn breaking - yep, I've done that!)
Then keep joining squares more squares together, either to form rows or if you prefer blocks of squares.
STEP TWO: JOINING SETS OF SQUARES
Start by joining the first squares together as above, working right up to the corner chains. To do that you work across the stitches of both squares. So insert your needle into the top of the last corner chain and then out of the first corner chain of the next square.
Sometimes you do need to gently pull the squares up or down slightly to get the corners to align just right.
For long joins you may need to use a few different pieces of joining yarn as long pieces do get weakened as your work from all the threading and pulling tight.
