Spray paint. I love this yellow mirror frame. These days you can find spray paint that will stick to almost anything. I do most of my home-accessory shopping at thrift stores, so I am a spray-paint addict. You can change anything you wish. I have successfully painted frames, shelves, birdhouses, candelabras and more.
Tip: In a well ventilated area, spread newspaper and get the piece ready for priming. Primer will make the paint stick better. Be sure to pay attention to drying times and temperature ratings before you paint. Don't rush! Paint takes time to cure.
