Cut the Crepe paper into
a strip about 2-4 meters long. Tape or glue the paper around the outside
of the cotton reel. Thread approximately 1 meter of string through the centre
of the reel and tie off. Hold the other end of the string and wave around
in long sweeping arcs to make wonderful patterns.
As you get better
increase the length of the streamer. You may also add more than one strip
of paper to the reel. Try using different colour papers!
