acrylics on denim

[http://users.livejournal.com/ziggy_/]

quick question...i want to paint the back of my denim jacket. i know fabric paint would work...but would standard acrylic paints made for canvas and such stay on or wash out even a little bit? if acrylics dont work, is fabric paint what people normally use? i'm doing one of those mural type things, not just a little picture, so i'd prefer not to use my small selection of fabric paints. thanks for your help!
