This is my first ever Moleskine. And now I did my first defacement (but not my first sketch.)
I put my name, address, etc on the flyleaf page that says, "In case of loss, please return to," and a little blurb about myself, as suggested (I think) by Ammon.
I'm almost afraid to start my first sketch. I've never worked in a moleskine. If I work in a spiral notebook and goof it up, I can just rip out the page. (Eek!)
