I amused myself the other day by making some little origami foxes using this diagram by Mark Leonard, and a whale using these traditional instructions. (The website where I found the fox is apparently no longer active or I'd link to it.)
I thought maybe these animals need a place to live, so I made them each a habitat.
You can download and print these backgrounds, then glue your own origami animals onto them if you like. Framed, they'd be cute in a kid's room.
Download the woods.
Download the sea.
Print out the sheets and leave them 8 1/2" x 11" or trim them a bit to 8" x 10", a more common frame size. The animals were made from 6" standard-size origami paper. A full square for the whale and a half sheet for each fox. You could also shrink everything to mini size and make some little cards if you have nimble fingers.
