I buy sketchbooks a lot. And use them! But mostly out of necessity. But nothing NOTHING is as satisfying as drawing on random scraps of paper. My desk (and life) used to be nothing but random scraps of paper. Unmanageable endless sheets of idiotic crap and genius moments. Someone once asked why my work space looked like a hamster cage and forever after I have called these sheets #HamsterPeePages (at Death Star)
