Summarize:

Before you add your varnish, use paint to create an additional decorative design along the outside of your beads. For extra texture, use puff paint which dries in a bubble-like form above the surface of the bead. To make your beads sparkly, use glitter glue or loose glitter over the surface of the paper. Add the glitter before your final coat of varnish to keep it from rubbing off as a result of wear and tear. Try adding several coats of glitter in different colors for a lovely rainbow effect. Don't thread the beads on string; use string to create a decorative pattern along the outside of the paper. Cut a small piece of colored thread and use glue to wrap the exterior of the bead with the string. Use several pieces of string for added color and texture. Use colored florists wire to thread the beads and create pretty spiral or geometric patterns around the outside. Run the wire through the middle of the bead, and then bend it to shape around the bead. Use a translucent nail polish or watered down paint to coat your bead in an additional color. Adding the glaze will create a light, semi-opaque layer of color over the paper. You can also use watercolor paints for this.
Add paint. Put on a little glitter. Wrap the beads up in string. Use a little wire. Give your beads a glaze. Finished.
