Paint the boo sign with a few coats of the black chalky finish paint. You will probably need one or two coats to get good coverage.Let the paint dry completely before moving on to the next step.
Sort your googly eyes into colors while you wait for the paint to dry.
Decide which color eyes to glue onto each letter. Use hot glue to attach each eye. Make sure to vary sizes!
Pull off glue strings to give your sign a finished look.
