What is the best way do distress a jean jacket?

I have this jean jacket that looks like the 90s in a bad way but it fits perfectly. I really wanna distress it so it will look better but i don't know how to do it with what I have at home because I don't have any sand paper. Any suggestions are greatly appreciated.

if you don´t have sand paper you could also do it with a cheese grater, well thread banger explains it better http://www.threadbanger.com/post/472/how-to-make-vintage-jeans-using-coffee-grounds , just use the techniques that apply to your jacket
