This isn't much different from all the other matter foldables out there, but I figured I'd post it anyhow. The stickers (ie hole reinforcers) we used were just something I had on hand. I'd like to find smaller stickers next time, so they can fit more on to really see the relationship of molecules and the space between them. The foldable is just a sheet of paper folded in half landscape-wise. Then, the fold is glued together about an inch down, to create a title area. They measure in 3 1/2" from both ends to create the cuts for the flaps.
