I've been wanting a convex mirror forever. An attempt at making one was was somewhat satisfying, and you can check out the tutorial HERE.
But not quite the look I was after. And then on a recent trip around my local thrift stores, I found this clock with a convex face ~ I don't need a clock, but I do have looking glass spray paint. $3 and the clock was in my car.
I used painters tape to cover the wood frame.
Using an x-acto utility knife, I cut the tape away from the face of the clock.
I then sprayed the glass surface with three light coats of Rustoleum Looking Glass spray paint. And now I have my convex mirror.
