This isn't new I know, but new to me - I recently found sm, med and
coarse sanding sponges at Harbor Frieght for a few bucks for a dozen.
They are great but the fine isn't fine enough. Ace has
sandpaper-backed sponges in fine grit but they are $4 EACH.
So I figured a way to make my own: Bought a grouter's knee pad from
Ace ($3 -- 7/8" thick closed cell foam) and cut it into 12 small
"bricks". Used spray adhesive to glue onto the foam different grits
of sandpaper, including crocus cloth.
I'm really pleased with the results.
Also, a friend told me about little sponge sanding disks sold at
beauty supply places, for manicurists. They are also great. (Never
would have thought of that, having only once been to get a manicure,
on a cruise - don't ask - and the poor girl was so horrified at the
state of my fingers and nails that she was exclaiming and showing the
OTHER spa workers!).
