End eyestrain when you’re hunting for the right wrench or socket. Wrap each one with a couple of layers of bright-colored tape, then write its dimensions on the tape with a permanent marker. (After a bit, you’ll remember the colors and their corresponding sizes and won’t even need the numbers.) Your eyes will thank you each time you change the oil, assemble that new wagon for the kids or work on the lawn mower. Thanks to reader Jason Nash for this visionary tip.
