Trot over to your favorite school supply store for a whole bunch of washable ink pads in different colors.
Toss a few fine-tip markers into your shopping cart.
Set up the wreath, the ink pads, and the fine-tip markers.
Add a small visual poster so that everyone can see what to do.
What to do?
a) Fingerprint the color you like onto the twig you like.
b) Write your name and draw a thumbody by adding some basic physical features a la Ed Emberley.
