You can find these fairly inexpensive metal trays at estate sales, thrift stores, and antique shops and a great way to re purpose them is to turn them into bulletin boards/inspirational boards. They not only help keep you organized but, they add a little vintage whimsy to your room. To give the project further whimsy you could create one of a kind magnets. The button magnets displayed above were created by my dear friend Stephanie of My Piper Dog.
