2 projects in one.
First is a shelf I fashioned from an old Football Stadium Seat to hold towels for the beach or pool, and the other is an old mail box that I've fashioned to hold a nice beach towel as well, Now all I need is a sign saying "this way to the pool", and some warmer weather.
Variations of this project. You could fill the mail box with sun screen and other necessities for outdoor swimming fun. The shelf could be useful in many areas of your home, In the kitchen, as a place for a key drop inside an entry etc.
I've used the mail box idea in the kitchen as well.
