Foamies pretty thin and flimsy though. I wanted to make a rigid prop. I also don't want to resin or sand anything. That being the foamies.
I was thinking about using the Eva 1/4" foam I use for costumes for parts like the cage but I opted out.
That could have probably worked with some cardboard backing on the inside. Once sealed and painted, weathered it might have looked decent.
You should give your foamies project a shot.
