[Granny Square]

First, when you sew something (machine sewing or crocheting), you usually  put the right sides together so the sewing part, which might not look as nice, is in the back side of the piece.

I started to describe this, but decided to draw a pic.  I'm drawing the chain as a sideways V, with each loop of the v a different color.  When you sew together, you want to insert the needle under the wrong side loops, which are on the outside, because the right side loops are together on the inside.  Insert the needle under the bottom grey loop, skip the 2 black loop, and put the needle under the top grey loop (you could do this in the opposite direction as well, needle under the top grey loop, over the black loops, under the bottom grey loop). It's a whip stitch, leaving the inner loops free. I hope this helps.
