A good idea for a small bathroom, under hanging shelves for things like cotton balls, cotton swabs, etc. Also great in the kitchen, for a spice rack over the stove. Just hang jars from bottom of the cabinet.
The visual is self explanatory for some with the skill to wire or repair a lamp or light fixture. This would make a delightful kitchen light over a small breakfast nook bar or table. The shadows cast on ceiling would be a neat bonus.
