When I was a kid (I mean, wee- like 3rd-4th grade), I went through an obsessive book-making phase. I would fold in half small stacks of notebook paper and stitch the spine, and make a nice little notebook. Then I'd get bored of it, lose it, and make another. I probably made 50 of the stupid things.
Never went any further, though, but it still fascinates me.
