Business card
When wrapping up a session, give kids your business card. Let them know that if they have other ideas or suggestions later, they can ask their parents to email you.
Why this technique
A business card is a very adult thing, so getting one makes kids feel special and important. And they should feel important as key experts in your design process! Plus, it’s a bonus that they’ll have a way of getting in touch with you again if they want to share additional thoughts.
