They fill up the mailbox…and then, they fill up the recycling bin. But now Duy and Tramy Nguyen have come up with a way to make snail-mail spam appetizing—and even exotic: turn it into fantastic origami art. Their beautiful projects are specifically tailored to the dimensions of those flyers, ads, and other unsolicited offers you’d normally throw away. Even beginners will be able to transform junk mail into extraordinary creations. The Nguyens start with an introduction explaining how to interpret the symbols and lines in their instructions and to make basic origami folds. Paper crafters can then put their skills to the test with 18 designs, including a bow, heart on a stand, and a cool Halloween skull.
