Summarize the following:
If you want to make a larger or smaller cube, just use larger or smaller square sheets of paper. You can find origami paper at most craft stores or online. If you don’t have origami paper, you can use regular copy paper that’s been cut into squares instead. Start by folding each sheet of paper in half. Then, continue making the folds until you end up with a small folded square. You should have 6 small squares when you’re finished. Each of your squares will have 2 end flaps and a center fold. Slide the end flap of 1 piece of folded paper into the center fold of another piece. Then, slide the end flap of a third piece of paper into the other side of the center fold. As you continue adding the other pieces, you’ll see the shape of a cube starting to emerge. Continue until you’ve connected all of the end flaps from each piece of paper, and you’ll have a cube! You may need to bend the flaps to fit them into the center fold.

Summary:
Start with 6 sheets of 6 in × 6 in (15 cm × 15 cm) origami paper. Repeat all the above steps with the 5 other sheets of paper. Fit the pieces of folded paper together.
