When I was about to go out to buy some snacks this afternoon, I didn't see my favorite slippers which usually in front of my front door. I searched for it for a while until my daugther came from outside and she wore my slippers. Then I got the idea to make this slippers papercraft :). It called "sandal jepit" in Indonesia, made from flexible rubber. It's cheap and available on many colors. It's commonly colored blue, red and green.
