This is a cute, easy and inexpensive gift idea!
If you have an old mirror laying around, turn it into a chalkboard quickly and cheaply. Just buy some chalkboard paint at your local hardware store...should be about $6.00 a can...and one can will do alot....and paint the surface of the mirror with it. Voila! Instant chalkboard!
Other ideas/surfaces for making chalkboards:
picture frames (cut a piece of masonite board that fits inside the frame. Paint the board with chalkboard paint and let dry before putting it into the frame.)
Old Cabinet doors
stiff poster board
