Steve Wintercroft is a builder and designer. There are plenty of his works which deserve a mention, but for now, we are all praise for his 3D Paper Masks. Using old cardboard, parcel tape, a pair of scissors, and as he asserts, with plenty of hot tea, he created a marvelous fox mask.
Encouraged by his own creation, he created a few more masks, mostly wildlife sort of thing. It was the Halloween costume dilemma that forced him to sit down and create something unique.
Perhaps, he understands how desperately people look for costumes every Halloween, therefore, he has made his designs available on Etsy shop where anyone could buy the template, print it out and stick it to whatever material he/she wish to use or reuse.
All it need is a consistent effort of 3-4 hours to tape it all together. If you bought the idea, then do check rest of the details here.
