My homemade Magneto costume for Halloween! I got the helmet template from Dali Lomo - who does some amazing superhero mask stuff with cardboard. Check him out!
The mask is built with cardboard & a hot glue gun, then applied paper mache, then applied plaster strips. I had to add an extra strip of cardboard down the middle of the helmet to accommodate my giant head. The other accessories are all spray painted cardboard.
The gloves and boots were built around gloves and shoes, with cardboard strips to add length, then colored duct tape to finish. One of the gloves had magnets on the fingers to lift up (small) metal objects!
