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