I whipped up some crafts with my daughter the other day trying to use things we have around the house.
We came up with some chalkboard cupcake toppers, a Valentines Day card with chalkboard, and used some Japanese masking tape to decorate the card and some of the shelves on my craft cupboard.
To make the toppers or card, spray some chalkboard paint on a sturdy piece of card stock. Let it dry then cut it up for anything you want to create. For the toppers I used some double stick tape.
