Lost in her imaginary Cave Astrid, kept mumbling to herself "I'm a little adventurer and i can do this" gradually more of her could be seen as she emerged from her cave of sheets looking bedraggled, and in need of a sustaining snack. After a quick refuel she headed back to play with her friend Owl Bear and Sage Mage.
The main thing with a screen printed shirt is just throw it in a cold water wash, don't use hard core detergents or bleaches........... oh and if your really super then turn them inside out and you will get more wear out of them. But remember Dirt and Kids are meant to be, should be, and need to be, its all part of being an adventure!:)
