I do a lot of fret work, both on plaques and boxes, and it took a while to figure this out but now it quickly eliminates almost all fuzzies. I sand both sides of the pieces before I even apply the pattern and start cutting. Some of the exotic hard woods are not that much of a problem, BBPW more so. I blue tape as many cut out pieces back in the pattern as I can. This forces the fuzzies out the back. Before removing any tape, I sand the back with a orbital hand sander and then use a scotch brite (red) sanding ball on a drill and go in all directions on a flat surface. ( I buy these from HF for about $10) ( I tried this on my drill press but pushed too hard and broke off some fret pieces. I don't do that any more). I remove the tape and then the pattern and most pieces fall out or I push them out with a x-acto knife. In most cases I shellac my projects. It seals the wood but also lifts any loose fibers from the wood. I give a light hand sanding again with a piece of 500 sand paper and blow it off and tac cloth before applyng final finish.
