This week I'm doing an origami cat picture frame. I used a 2.5x2.5 inch square of computer paper to see how it would look. I recommend doing your first model on a larger square as the instructions were a bit confusing. Your cat may look different depending on how you fold steps 3, 10, and 11. Don't be afraid to give it some personality, and don't get discouraged if your first one looks like frankenkitty.
The instructions are from en.origami-club.com and can be found elsewhere on the web.
After folding (and preferably decorating your cat) you can glue it to any old picture frame and stick a picture of your pet inside!
