350 Tiny Paper Foldable Airplanes

This is a page-a-day calendar (it’s from 2008 so can’t be used as a current calendar but you’re supposed to cut off the top section with the date on it, so it won’t matter when you’re making the paper airplanes). Each page features a cool abstract design that can be folded into the airplanes, based on 1 of 30 aerodynamic models, following dotted lines on the back (general directions are also included). The first January 1st page is missing. Such a great set to keep everyone on the family busy!
