If you are willing to risk personal injury, you can make these Christmas ornaments.
In both school and at home I remember making ornaments for the holiday. My mother has always been creative (the license plate on the front her car read “Crafty Lib” for years) and when it came to a inexpensive way to occupy our time at Christmas, she would help us with projects.
Take the lids from soup cans. Smear glue on the sides of the lid. Sprinkle colored glitter on lid. Let dry. Make a hole in the edge of the lid and loop a piece of twine through it. Presto! Homemade tree ornaments!
(NOTE: I know the edges of soup can lids are sharp, but I grew up in a time when parents told children to be careful and we quickly learned that NOT being careful when told usually meant we got hurt. It seems like a lesson that needs to be learned.)
