Simple and whimsical, this card from the Persechini family of Overland Park, Kansas, is easy for kids of all ages to help create.
You can use thumbprints to create Santas, trees, candles, people--you name it.
Have each family member choose a color and use ink pads to make several thumbprints.
Have your kids add antlers, legs, and so forth to make the thumprints into reindeer.
Scan their art onto a home computer and use a publishing program like Microsoft Greetings to arrange the reindeer and print the cards. (Most copy services will also scan and save to disk images.)
