Bob Clagett of iliketomakestuff made He-Man's shield replica from Masters of the Universe using cheap foam floor mats. This is only his second foam prop build and he learned all about foam fabrication from Bill Doran (Punished Props). If you want to learn more about EVA foam and armor creations, you can purchase Bill's Foamsmith books here.
Bob will be building the He-Man sword in the future. Check out the detailed video below to view his impressive build.
