Birdhouses/Fairy houses - cute craft for kids - paint a toilet paper roll and cut out a window. Trace a plate onto stationery and cut out circle for roof. Tie a button on the end of a string, pull string through tip of roof's cone to anchor. Make a loop in string to hang onto tree.
I found this easy but very cool project on a wonderful blog called "TeachKidsArt". It was a very do-able project for my participants and they loved the 3-D results. A different spin on a Valentine's Day art project.
