Printing has been around since about the year 200AD, and was in use for centuries in the Middle East, Europe and Asia -- especially Japan -- before spreading around the world. Printmaking is still alive and well today, and many artists use a variety of printing techniques to create unique and beautiful works of art.
If you want to try your hand at printing at home with your kids, the most convenient method is the humble rubber stamp. If you happen to have some rubber stamps lying around the house from your scrap-booking projects, it is time to take them out! Try combining the images to make a story. What patterns can your child make with the stamps? Can your child combine stamping and drawing to make a picture? For more rubber stamp ideas, read Cool Rubber Stamp Art by Pamela Price.
Of course, if you have no stamps at all, fear not. TLC Family and Kinderart have plenty of suggestions for making your own stamps and printing blocks. For more ideas read Joe Rhatigan's Stamp It!, The Usborne Book of Printing and Printing by Michelle Powell.
For any grown-ups who want to try printmaking and stamp art, try The Instant Print Maker by Melvyn Petterson, Creative Stamping by Sherrill Kahn, and, for some history, The Woman Who Discovered Printing by Timothy Barrett.
Also, if you act fast, you can see some cool prints at the University of Michigan Museum of Art's exhibit Sister Corita: The Joyous Revolutionary. Admission is free!
