[help] What's A Good Brush For This Effect?
google grunge brushes
yeah, i found a bunch. i was hoping for some recommendations. 
The best ones are made onyour own. Throw some Dirt or anything you want on your scanner. Oh yeah, make sure you cover your scanner in cleophane before you go toss dirt on it. 
no scanner.
i'll try out some brushes. then i'll bug my gf and ask her how she does her wallpapers.
