the edges to form the flaps. you can see the thinner side flaps. those are too long so cut them at the first score. i also trimmed the sides at a bit of an angle so the lid closed nicer. once you get those small flap pieces cut you can see the other pieces take shape. if you have trouble "seeing" what it should look like, just find a box in your home. a color crayon box would be the best example. i also took a couple tiny wedge slices off the ends of the big flap too. i do that to make sure it goes in the box nicely.
