I've been using air conditioner foam insulation for my camera case. It works OK, but I need to use three strips of the stuff to completely fill my case. Anyone have any ideas where I can find a similar foam but in a bigger size, say 6"x6"x2"?
The foam I use is like your couch cushions, it's soft
use an electric (fillet) knife to cut it, you can sculp what ever you want with one of those electric knifes, it slices that foam great. I make the holes a little smaller for the cam, etc so it "wedges" or sticks in the foam
