From Better Homes and Gardens:
Do you have small ornaments or figurines that you no longer use but want to display? Try creating a still life with an inexpensive clear dome. Use a small chipboard circle (cut to the size of the dome’s base). Arrange small items — old ornaments or nature figurines, for example — onto the chipboard, adhere them in place, then add small pieces of tinsel or garland. Glue the dome to the chipboard base.
