You will need to cut the graham crackers in half using a knife, forming a stack of 8 squares (this is the most that will fit into the jar at one time). I wrapped these in a small piece of saran wrap, and when placing in the jar, place the pretty side out so that "clean" side is visible from the outside. Next, layer chocolate on all three remaining sides of the graham crackers. You will be able to place about 6-7 squares of chocolate. Next, add your marshmallows in 3 layers (place them long side up to fit best and look tidy in the jar).
