Cut out several oval shaped "eggs" from colorful construction paper. There will be two "egg" shapes for each egg on the garland, a front and a back.
Decorate however you want (only decorate one side).
Match the fronts to the backs. This will give the children practice sorting.
Lay your string flat and put one "egg" on either side of string and glue pieces together.
Let your garland dry and hang it up!
