Sometimes a hole is more than a hole; it’s a storage solution. For example, a 1×4 piece of wood mounted horizontally on the wall is perfect for screwdriver storage if it has well spaced, correctly sized holes drilled in it. The same concept works for nut drivers and chisels, but you’ll want slightly larger holes. A well-placed hole can also be a great mounting point for an articulating arm lamp. And finally, a really novel idea: store glue bottles upside down by drilling a hole in a shelf that’s slightly larger than the glue applicator end. This way the glue is ready to go when you are.
