I make foam armor and props from my own craft room, recently last year from a pre fab garage to a full conversion
I use Eva foam, different thickness, and Eva foam clay, plastazote (ideal for diffusing led light)
Use a dremel, beltsander, heat gun, wood burning tool
Glues contact adhesive, foam hot glue, latter for securing fragile detail and securing straps
Paints flexipaint, they do not crack, unlike spray paint which would,
I also use worbla @ thermal plastic, worbla beads, pearly (for detailing) or clear (for led light lenses)
Here's my latest project I'm working on
Black dragon helm
