Having lined up your middle squares of the first row ready to be sewn up, thread your needle with some yarn. Use yarn that is thinner than the yarn used to make your square. I used DK yarn to make my square, so, to sew the squares together, I'm using 4-ply yarn.
1. Now I'd like you to put your needle up and through the bar, on the edge of the BOTTOM LEFT hand side of that square, as I've done in the photo above.
This time, you will be taking your needle up and through the bar, in the chain that is at bottom RIGHT hand side of your square.
3. Take your needle through and up the side of the chain, as before, on the edge of the next stitch, of your RIGHT hand square. The square you worked into first.
Sometimes it's difficult to find that 'bar' on the edge of your crochet, so as you can see in the photo above, I have just gone through and up, the outer edge of the next chain up, in that square.
Now for the fun bit, making your stitches invisible!
Now you can start pulling gently on the yarn emerging from the top of your ladder.
I love this bit, when the stitch goes 'invisible'.
Anyway, lets carry on joining squares shall we?!
I'd like you to repeat stages 1 to 5.
Do exactly as you did with the first two squares.
So now we're going to do the outer two rows of the scarf.
So when you come to sew up the horizontal lines, make sure you start and finish with the middle two squares only, otherwise your outer squares won't flap.
As with the vertical rows, repeat stages 1 to 5, remembering to start at the edge of the second square in, as above.
And there you have it! One section of your scarf is complete! Well done.
