To keep track of small parts with holes in them, such as plumbing washers, steel nuts and washers, reciprocating-saw blades, and so forth, I use good old-fashioned shower-curtain rings. Just spring open the loop, thread on the part, and you’ve got the parts corralled in an easy-to-access fashion.
For tool storage, I’ve found that plastic storage tubs are the ticket. I have different sizes, with one for power saws, drills, extension cords, tool belt, and small hand tools; and one for glue, caulk, caulk gun, sandpaper, and sander. The plastic lids keep the tools and materials both clean and dry. Grouping the tools keeps things organized, and the tubs stack and store easily. I’ve found the 10-gal. size to be the most useful.
