These can be purchased at your local arts and crafts store. Simply glue the lights to the inside of the sea shell and youre done! Were thinking this would look great at a beach house or in a beach-themed bathroom! For more awesome upcycling ideas like this, find Dirty Work Austin on Facebook, Twitter or Google+.
