I've been drawing since i can remember and being am artist mean your sketching stuff down at all hours of the day so as sad as it sounds your black book becomes one of your best friends. so its always sad when you've filled one and it looses its place in your back pack. this book has seen more and traveled farther than most people in my home town.Fact.
but on the good tip i get to start a fresh new one soon to be filled with ideas i haven't thunk up yet.
