WHy not experiment? As ringring says, it will give you an appreciation for the work of denim laundries like Bart Sights and Martelli.
Most commercial laundries have inflatable templates to position the whiskers, but you can do this yourself by simply wearing them, squatting etc, and you have the luxury of time. I would suggest you use stones or a brush, or several different ones, rather than sandpaper, and don't spend too long on any particular area, keep moving around, and varying your tools and technique.
Then at some point, scrub the kitchen and bathroom floor, get some dirt in the knee fades and elsewhere. Not all of it will wash out and that helps too.
