It can be a pain to deal with the scratches, nicks, and smudges that invariably appear on painted walls and trim; retouching means digging out the right can of paint and opening it up and stirring it without dumping in a bunch of rust or dirt. That's why we like the Qwikie Paint Touch-up Tool. It combines a small container for leftover paint and a screw-on cap with a built-in brush. Get one for each shade of paint you've used in your home. Available from Hans Plads ($4.99 for one, $15 for three; or 866/227-3861).
