These are just a few examples of the many products available at the lovely Australian-based store Upon a Fold. They sell unique paper artistry from around the world including all sorts of amazing pop-ups, objects, cards, books, stationary, and notebooks. If it fits into the world of folds, it's here. So, even though it's quite pricy to have things shipped from Australia to the U.S., it's still a lot of fun to browse through all of Upon a Folds amazing products. They also has an incredible blog, which has quickly become one of my favorite reads and sources of inspiration for all things related to paper art.
