use a slice of bread on a painting
I don't know where to place this, so sorry if it's in the wrong forum.
I'm looking for some way to transform a slice of bread I made myself to a version which does not go bad - ever. It's used for display purposes, I want to create a poster with real food in it. I know some bakers have plasic bread up front on their windows which of course never goes stale. I am searching for something like that, but I'd like to make it myself.
So my question is: can I simply spray plastic paint onto a piece of food?
What do I need for something like this?
I hope the question is clear enough :)
