I make my own. Just download brushes off deviantart and mess around with white brushes on a black canvas.
I use 100% stock ps brushes and some ive made with stock ps brushes and i havnt touched another persons custom brushpack since i started out
i just found out how to do some more background stuff so im goign to start making my own for good now
I mostly make my own... only times I don't use my own BG are when required to as a condition of something or when doing a photomanip... I voted make since that is effectively what I do, even when I have to use another BG I make a decent FG to go over it so yeah...
Getting your backgrounds off the web is known as ripping. We have a zero-tolerance policy in regards to that. Are you confessing to ripping?
