Keep bulbs in see-through shoe box–size covered bins on a closet shelf. Label the bins by wattage—40 to 60 watts, 100 watts, and so on, says Amy Brady, an organizer in Austin, Texas (theclutterconsultants.com). Use one bin to contain specialty bulbs, like night-lights, high hats, and halogens. (Set of two medium clip boxes, $10, stacksandstacks.com for info.) Closets already stuffed? Stash bulb bins on a shelf in the garage.
