I'm sanding my guitar. just a little paint near the edges, not all the paint's gonna come off.

I didn't wanna hijack another thread but coincidentally we're sanding.

i have no tools but sandpaper. are there any ghetto tools i can make with stuff i can find around my house? And i also need some sanding tips like what strength to use first, then the next and so on..

i have these:240, 150, 100, 60.
