I've been plodding along with my prop making hobby recently and have been doing quite a few with foam, because it's easier for me to work with than mdf / timber. I've found it to be a lot of fun and would love to see what other EVA or general foam based props are out there all compiled in one place, so I hope you will add your own.
I know a lot of people seem to make armor out of EVA, but I've been making smaller props, books, weapons and accessories and it's loads of fun.
Here's a few I've done so far:
Just finished Mal's pistol from Firefly this week:
Designed this Warhammer 40k tome and made it:
Cthulhu Mythos inspired tome:
Crown and Tankard for LARP:
I've got some others but I don't want to bore you all!
How about you, foam props FTW!
