There's a set of children's books I really love called Not a Box and Not a Stick where a little animal imagines all the things a box or a stick could be (a robot suit, for instance, or a sword to fight dragons).
Since I got this hat, I've been noticing all the things it is besides a hat at my house. In the past two weeks, it's been a mask, a curtain for playing "peek-a-boo" with Ani, and, memorably, a very small boat just the right size for a toddler to paddle across the living room carpet.
The hat's gotten in on the game too - last week at the beach, it seemed to think it was a kite, soaring skyward with a particularly hard gust of wind (and then landing in the waves, of course. Happily, it dried out nicely, looking none the worse for wear).
