Do you have some old frames that look, well, outdated?? I've done it once, and I'll probably do it hundreds of times. Just give that old frame a couple of coat of Krylon indoor/outdoor paint- the colors you can choose from are amazing! And don't make the mistake of buying it from the craft store. Walmart sells it cheap. Do the spraying outside far from anything you don't want overspray to get on. I spray my frames in a box with a drop-cloth underneath, usually in the garage if it's too hot/cold/windy outside. Tape off any part that you don't want painted, the glass didn't come out of these frames, so I had to tape them off.
Add a beautiful piece of art (this one is an original by my daughter) and hang in the room of your choice. This technique also comes in handy when you have a bunch of mismatched frames that you want to hang together and look cohesive. Spray paint! It's amazing ;)
