How to Make the Pom-Poms
You'll need tissue paper and 24-gauge white cloth-covered floral wire.
1. Stack four sheets of tissue. Cut a 10-by-5-inch rectangle, going through all layers. Make 3/8-inch-wide accordion folds.
2. Fold an 18-inch piece of floral wire in half, slip over center of tissue, and twist to secure. Trim ends of tissue (round edges, pointed ends...... whatever you like.
3. Separate layers, pulling away from center one at a time.
4. Bend wire into a loop to fit around napkin, and twist end around loop to secure.

So many uses for these.  Pick colors that go with your decor and get creative.  For the look on the left, secure with glue on to a styrofoam sphere.  On the right, glue the pom poms on to a ring.
