My friend has a 10-year old son that plays the drums, and he recently had a talent show at his school which I attended. He killed it, btw. Seeing him perform on a stage inspired me to create something different in a thank you card for kids.
The focal image is the cutest drummer I've ever seen. I think it can teach kids to send out thank you notes at a very young age. It's a custom card with their specific interest; they'll want to share with friends and family. I'll try to come up with other designs that will inspire kids to write mail, before they're allowed to get onto Facebook and sent notes that way. :)
