I want to make my room's wall or maybe just a part of a wall look like rock (lava rock?). Then carve hawaiian petroglyphs on it.

What is the cheapest, easiest way I can go about it? I don't own any "man tools" and I've never done any craft. I did a search on the web for 'how to make fake stone' but it sounds too complicated FOR ME with all those chicken wire and grout mixing.

I was thinking of using styrofoam sheets, then carve my symbols with a 'soldering iron'? Then paint it with those stone spray paint.

Now the problem is, the styrofoam sheets would be too nice and FLAt. How do I make it more 3d like a cave wall??

I read some where about some insulation foam. Can I spray this foam on top of the styrofoam sheet?

Thanks for any idea.
