A couple weeks back a commenter (Rane) referred me to "The Toymaker". It's a website with lots of free paper toy patterns to download. It's also where I got the pattern for the "window to fairyland"toy (picture above). There are patterns for boxes, cards, and educational toys on the site as well. I definitely recommend checking it out.
The fairyland toy was really simple and quick to make. I envision it used for a favor or craft project for a fairy themed birthday party. Perhaps one could glue a picture of each child attending the party to the inside of the toy. Glitter and embellishments would also look nice glued to the fairy picture.
