My daughter made a wreath out of pipe cleaners and beads. They used a red pipe cleaner, added the beads leaving enough room to make a bow out of remaining pipe cleaner. She also made a candy cane moouse. It is simple an oval piece of felt with two small cuts to insert ears- more felt-long oval shape, and 2 small slits to insert candy cane. It sits on the tree braches and is really cute and easy. You could have all the peices precut and ready to go at the party. You could make wreaths out of paper plates. Cut the inside of the plate out glue construction paper that has been torn around the edges(maybe the teacher can supply the paper?) If everything has to be store bought could you "make " the treats in class? One CHristmas we made rice crispy treats( melt butter amd marshmallow in crock pot) and decorated them as packages. We used sprinkles and red licorice. It was a huge hit.
Hope these help a little.
