I really like the Paris Craft hands idea! (timely too with the George Segal
video just coming out)
Here is another one...What about a "Story Quilt"--inspired by the work of
Faith Ringgold. Students could use fabric transfer crayons , acrylic paints,
paint markers --what ever. You could even include strips of student writing.
The piece can be hung on a dowel rod and displayed in library or some other
place of honor.
Of course--Ceramic tile "murals" are always a good idea, too.
