hey, advanced sig makers, i seem to have a major flaw in my design: i can't play with the background of a sig. i feel (even if you don't) that im pretty good with renders and text. my problem is that i have no clue how to add good brush strokes or add other background effects. all i know is clouds. can someone make a tut about how to make a good background and not just say "add a good brush here", like add a lot of details about how to make brushes look different or how to change the backgrounds appearance. rep will be given, of course.
