Concrete wine rack. Make a wood box (cheap particle board is fine), use 4" PVC (spaced at least 1" apart) and fill with concrete. Add color tint if you want something other than gray. Wait at least 24 hours then carefully remove wood and PVC.
Rethink a wine rack& purpose, and you& come up with a multitude of novel ways to put it to good use. In this kitchen cabinet, a tabletop wine bottle rack now holds waterbottles behind closed doors in tidy grab-and-go rows.
