Ayako Kishi made this paper mobile inspired by the season Autumn featuring squirrels, owl, fruit basket and colorful leaves. You can print the step-by-step instructions on assembling the paper mobile and patterns for front and back. All you'll need is some string to tie everything together. It'll make a great educational toy or used in a nursery.
