Here is a tip for when you are painting around mirrors or on glass doors like on hutches to avoid getting paint on the mirror or glass. Just take a deck of cards and place one at a time around the edge. I have learned that if the card fits snug it's good but if it doesn't fit snug it helps to add a few cards on top of each other in that one spot to help avoid the cards from moving.
Once the cards are in place you can paint! It sometimes helps to hold the edge of the cards while painting to avoid them from moving. Take the cards out and you have a nice clean edge!
