A model design by Simon Andersen

This model, the Little-Wings Envelope by Simon Andersen, is easy to fold, practical, and minimalistic. When we make it with a US letter-size, piece of paper, this model can be used to send cards during the holidays, for invitations, or birthday greetings. With a larger piece of paper, this model can be used to present a diploma or award. Experiment with rectangles of approximately similar proportions but differently sized papers.
