I started with this $7 mirror from the thrift store:

I spray painted the frame white ($3) and then added four coats of magnetic paint (kind of expensive, a quart was $20) straight onto the mirror. Then I sprayed two coats of chalkboard paint ($5) on top of the magnetic paint. That’s it! It’s not super magnetic, but it does the trick. Some spots seems to be better than others (as you can see from our name falling). I have lots of extra magnetic and chalkboard paint so I’m thinking of more projects to do.
Total= $35
It’s up in our kitchen and I just love it!
