Here's a simple, inexpensive and quick Christmas ornament for kids (and adults) to make. My four year old daughter made the one pictured above in about ten minutes. I did have to help her for one part which I share in the directions. An older child could do this completely on their own. They could even make the ornament more complex by creating a pattern with the pom poms. There's lots of possibilities with this project so get creative and have fun!
One styrofoam ball with a 2 inch diameter
50 small twinkle pom poms (approximately) - you could use regular pom poms as well
50 straight pins (approximately)
Place a pin through each twinkle pom pom. You might want to do this part yourself depending on the child's age. I did this step for my daughter.
Fold ribbon in half and tie in a knot at the bottom to make a loop. Pin the knot of the ribbon to the styrofoam ball. Cover up ribbon ends by placing the pom poms over them. Continue to push the pom pom pins into the entire ball until none of the styrofoam is showing. Done. Supervise young children when they use the pins.
