Was in a garage once and saw a neat idea, the guy saved jars, baby food, pickle, all smallish jars, he nailed the lids to the bottom of a shelf and had nuts, bolts, nails and other small stuff in them, if he needed something he'd just unscrew the jar from the lid. Didn't take up much room at all and nice having it all organized.
I reuse empty prescription bottles for small fishing stuff and crafts.
