I washed them really good and then primed them. that was all the prep I had to do, (no sanding, yeah)I chose to use Valspar black and cream spray paint. I sprayed them twice to get a really good, even coat. Then I went down to our local craft store and bought three decals. I put the two together and........TAAADAAA.
As you can see they aren't exactly on my fire place mantle (but they could be), but they're on a more important mantle, the back ot the toilet!!! You know when I walk in the bathroom and see them with that beautiful green flower in them, well I just smile.
