These designs are for a ukulele rack that can fit in a standard three-foot-wide cabinet found in many classrooms. The rack can be built with simple tools like a circular saw and a hand drill, and uses common materials found at most hardware stores. Each rack can fit 10 or 11 ukuleles in convenient compartments. Each compartment is padded with foam insulation, protecting your ukuleles, and making them easy for players to access. I built two of these racks, and wanted to share it with teachers who wanted a storage solution that would work with their existing cabinets!
