Push Pin Art
What you'll need:
Colored construction paper
Simple drawings with a dark outline (see photos for example)
Dot-trace the outlined drawing onto the white paper. Tape or staple the dotted outline to a sheet of construction paper. Have your child (who is old enough to carefully use a push pin) lay on the carpet or a soft surface. Then they punch tiny holes to make the outline of the art. When done, remove the white paper and display the construction paper on a window to let the light shine through the holes.
