When my kid and me draw on our car the theme is usually Monsters. And my kid is a very good monster drawer. All the designs you see on this site — except one — were drawn by her.
If, for whatever reason, you do not like the t-shirt you bought, you can of course send it back to Spreadshirt. I would really appreciate it if you could let me know as well why you didn't like it via twitter or email at tshirtmonsters[at]vasilis.nl.
