For the actual frame I bought (pre primed) casing. Basically the stuff the that you woudl use to frame out windows and doors. I bought and 7' and 10' piece and had them cut each of the four pieces to the size I needed.
First I had to cut my molding at 45 degree angles to form the corners of the frame.
Once all the pieces were cut I painted them. (Tip - Be sure to paint the back side of the molding as well because when it is up against the mirror you can see some of the back.)
Once the paint dried I applied a generous amount of liquid nails to the mirror.
Then placed the molding on the mirror and held it in place for a few minutes. I repeated this step until all pieces where in place.
The next day I used caulk to hide the small gaps in the corners where the pieces fit together. This caulk is awesome because it goes on pink and dries clear!
For $25 I think it makes a big difference, and it will be even better once I debrass everything!
