Here's what you need:

Paper clips
floral wire (you can use jewelry wire but floral wire is much cheaper and we in the WAHM.com test lab found it works just fine)
glue gun
wire cutter
needle nose pliers

Total cost ... pennies!

Cut a 6 inch piece of floral wire
Using your needle nose pliers, twist the wire into any shape you choose. We tried spirals, initials, question marks, flowers ... use your imagination.
Attach your wire design a paper clip with your glue gun. That's all there is to it.

Have Fun!
