This model came from a specific head design that I was working on, that was rather interesting due to its five spikes. Because this design needed a body, I quickly put the heads on a blintz frog base, and split the large point in the middle into many other smaller points. Although this is probably not the most creative design ever, it came out very nice, and the heads (the most important part of a three-headed dragon) are completely original.
This model was created using an 18 in square of homemade foil-backed paper
Variation with wings instead of 3 heads
