The dessert table is always a focal point so I like to use a painters canvas to create a lovely backdrop. I simply wrap fabric around the board and use heavy duty tape to secure it to the back. It's easy to remove later and use for another event.
I love that each table was unique and different but all coordinated together.
Create your centerpiece around a single element or idea and then use what you have (books, votive candles, figurines, etc.) to round out the look.
