This is my 1st day here, and thought I'd comment on the vacuum/nylon idea...but now I'm not sure I want to get involved.
At least with those last couple posts-ha!
I also use a white sheet that is attached to the edge of my work table and drapes down onto the floor a foot or two; usually anything dropped lands on it-but we all know how that goes.
(Depending on what you're using 'em for,if you buy Queen XXX size you save $$)
One can also use a white apron with velco, that snags under the edge of your bench.
Old timers used to have a wood framed canvas lined tray that pulls out and is nicely tummy shaped.
I guess the catch rate is near 100% once your tweezers are under control, and you're no longer dealing with 'pings'
