Love
this (painting on mirrors which reflect the sky).
Mirror "books."
Use one to display a gorgeous object on. (Scroll through
this post and you'll see a few.)
Set them at the
back of your shelves (2nd picture down) to bounce light; draw interest; show things from another perspective.
Draw on them with chalk markers. Use shaving cream on their surface. Or finger paints.
Can you tell I love mirrors?
