Inspired by artist Alexander Calder, these easy-to-make building pieces provide endless play for burgeoning art-chitects.
Cut free-form shapes of varying sizes from colored card stock or scrapbook paper (ours measure 3 to 5 inches wide and 3 to 8 inches long).
Snip two to four 1-inch slits into the sides of each shape. Build a sculpture by interlocking the pieces along the slits.
