On a hunch, I purchased AdaFruit's blank SMT component book, and hired my son to trim the labels from the Digi-Key kit and place them in the book. It works really well.
The books are so much more convenient than boxes of packets of parts, and take up much less space than plastic containers with bins or drawers. I could imagine this working for other through-hole parts (small caps, diodes, etc.). With a slightly different layout - say, horizontal pockets for labels with square vertical pockets beneath - it'd work for transistors and other components.
