i know kmart sells those craft boxes.
i'd just get some paper plates, cut out some eyes, and decorate it to make a mask...
or painting is always a winner at ours, the other day we did feet and hand prints..
if you're feeling really adventurous, put a sheet over your dining table, and underneath, stick 'planets' and 'stars' etc, and pretend you're in space. craft and a cubby in one.
have fun!
