Spinning tops are popular paper toys for children. This design uses six sheets of paper that are joined together, offering a unique opportunity for mixing and matching different origami paper patterns. This can also be hung for a pretty decoration. These would look very pretty hanging in a nursery as part of an origami mobile.
The traditional origami crane is perhaps the most popular example of origami projects. It uses a bird base, which is a square base plus two petal folds. Traditionally, folding a thousand paper cranes is said to grant you the right to make one special wish.
Next up is this lovely Modular Origami Cube Box, made from six "Sonobe" Units. These make great decorations or use as a gift box! If you use several different colored sheets of paper, they have a very pretty patchwork effect.
