I covered my thermostat with a box picture frame given to us as a Wedding gift. I used a simple 3-screw, swinging brass bracket to secure it to wall. Much cuter! PS It doesn't mess with the internal temp readings of our home, but I would be careful with this. A thermostat that produces some heat should probably not be covered.
Cover an awkwardly placed thermostat. 1. Purchase latchable box (hobby lobby has some great ones 2. Cut back out of the box. 3. Paint/decorate 4. Place on wall and create a lovely wall collage #thermostat cover #picture collage
