Take a individual size pudding cup from Jello pudding or similar type
product. Clean and dry. Take an Exacto knife and "drill" a hole in the top
to make a hole to put a hanger. Take a hole punch and punch holes
around the lip of the pudding cup. Cut gift wrap ribbon pieces 12
inches long. To incorporate some math, have the children cut the pieces themselves, measuring with a ruler to get the correct length.
Have them lace a ribbon piece through the punched holes and tying
them in a knot to secure them. Lace both ends of the ribbon
through the top hole, tie together to make a hanger.
Iridescent ribbon looks neat for this project but any ribbon will work.
