Show and Tell...

Ok, so I know the back of your block is not the most glamorous part but would someone who is already working on their block post a picture of what the back is supposed to look like???
I have read the instructions over and over, and I don't get how this is supposed to work. Do your stitches go through ALL three layers?
Please do show us how yours looks, for those of us who are trailing so far behind that you can't see us...pretty please...=)
