    Not quite as cheap, but quicker and I think, perhaps better, is
    simply to use the 3M Imperial Microfinishing film. unlike normal wet
    dry paper, this stuff is made with a fairly strong polyester film
    base. And it's color coded, so even if you cut very narrow strips and
    cannot then read the labelling, the color tells you what grit it is.
    I cut thin strips with just a pair of cheap scissors, and use it
    mounted in a saw frame. Works great. Doesn't last all that long, of
    course, but lasts long enough to do the job. 3M also makes a tape
    product that's very similar to this, but with two grits, either a
    combo of course and medium, or fine and extra fine (whatever those
    mean...), in two sections on each single strip. Nice, but since i've
    already got the sheets of the stuff sitting here, I've no need to go
    get a bunch of the precut strips...
