Happy Advent day 7!
We used the plastic charges we bought a couple years ago from the Dollar Tree (for $1 each). If you have some old chargers you want to upgrade, use those, or you can get some inexpensively as well!
Take any patterned or imaged paper design you like or have. You may even have paper scraps you could use. Try painting your chargers in your favorite color or to match your tablescape.
