Some trim from the Restore painted white (I let some of the wood show through on the trim),
and Command adhesive picture hanging strips were all it took. I stuck the trim/command strips directly to the mirror. They are holding well!!
I could have mitered the corners, but because I chose to use four different types of trim boards and because I wanted a more shabby look, I did not. The silver mirror was in the bathroom before--daughter wanted it back in there. It is not really useable hanging in this spot, but reflects the natural light well.
Cost for mirror upgrade:
Command Adhesive $6
Which brings the grand total so far to $59, and that leaves me $16 left to spend. I have one more project to show you to complete the under $75 bathroom makeover. It will have to wait until the end of the week, I have something fun for you all coming up tomorrow evening so make sure to check back in!
