Thank you cards

I posted after Christmas about sending out thank you cards, we weren't very good at it then. I wanted to be better prepared for Kit's birthday. I want him to be really grateful for any gifts and not expect them. He loves making cards. He often asks me to give him bits to make a card and occasionally we post them to people. I was contemplating what to do for thank you cards, but he obviously had decided already as he designed them himself (although I suggested the addition of googly eyes).

He's really into drawing faces with legs at the moment, they never have arms for some reason, although one of the later cards he introduced ears.
