I just found Flora Chang's shop, Happy Doodle Land. She sells an array of things that would ceaselessly delight anyone.
For instance-look at these stamps. Just look at them. I'd choose no. 7, 9, 16, and 22. Dude, how proud would you be if you got one of these at the top of your work? Estudiantes, you might get hooked up. Haha these make me so happy.
