What a great thread! You know, I take pictures of my projects at every turn. You could practically stack them up and make a flip movie of them. But I never, ever thought of taking pictures of the backside before sandwiching! And now that I've seen others' backsides (sorry, I couldn't resist that one) it is really a helpful thing to do. Just like taking a picture of the front to find things you don't see with the naked eye, the same concept works on the back of the front...
