You can experiment with different colors and designs. Repeated stamping produces lighter and lighter shades, which can be visually interesting. I would suggest this craft for preschoolers and older. (Logan, age 2, got a bit frustrated because he couldn't stamp full dots very well, and he gave up quickly.) Note: The stamp pad (see photo above) has gotten a bit messy over time with kid usage, so this wasn't a big deal, but if you like your colors to stay neat and clean, you may not want to do this with little ones. This was another cute idea I found on Pinterest.
