You can decorate clear Christmas ornaments in many different ways! One way is to use acrylic paint to create a design on the outside of the ornament. You can also use glitter glue, sequins, or rhinestones to add sparkle to the ornament. You can also fill the ornament with small trinkets, such as beads or tiny toys, or with artificial snow. Finally, you can use ribbon or wire to hang the ornament from a Christmas tree or other festive decoration.
