filtering specks out of paint

I always paint out of a small paint tray. When I'm done painting, I dump the remaining paint into a can that I use for excess paint (as opposed to putting the excess back into the original can). That way I can at least keep the original can free of what I call "paint boogers" - you know, those little bits of congealed paint that are accidently scraped off the brush or tray. So now I've got to figure out how to efficiently and thoroughly strain the "boogers" out of the paint in the can containing all the excess paint. I considered using some panty hose as a strainer, but I thought that might add some fibers. What do y'all recommend?

Thanks,

Jean
