Paperfolders can get prehistoric with the new collection by an international origami master. Ranging from the very easy to the low-intermediate level, 20 models include a tyrannosaurus, apatosaurus, pterodactylus, dimetrodon, quetzalcoatlus, protoceratops and other famous and lesser-known dinosaurs - all based on Montroll's singlesquare, no-cuts, no-glue approach.
