Many origami butterfly models exist but I haven't come across these ones before - Butterflies in Origami by Nick Robinson! Inside, the British origami master has hand-picked 20 lesser known, though wonderful, origami butterfly folds. These unique designs are from a variety of noted paper folders including the author himself. Each has large, clear diagram and text instruction, as well as colorful project photos. All models start with a 7 inch square. I really like the paper-to-model ratio that is included. Each design has a difficulty rating and the designs increase in difficulty. If you do get stuck, there is a link for each project to a step-by-step video tutorial. I was hooked after making the first butterfly. Dover Publications released this 128 page paperback October 17, 2018. Get your copy below!
