Clean the mirror with a glass cleaner and a soft cloth.
Measure the edges of the bathroom mirror using a measuring tape.
Use a saw to cut four pieces of pre-finished wood trim to the measurements you determined in Step 2.
Set your miter saw to 45 degrees and bevel the edges of the wood trim. This allows the pieces to fit together like a wood frame.
Apply a dime-sized dot of clear two-part epoxy to every metal clip on one side of the mirror.
Press the corresponding piece of wood trim to the metal clips
Repeat Steps 5 and 6 working your way around the edge of the mirror.
Allow the epoxy at least 24 hours to cure.
