These couple weeks, I've been carrying around a dip pen, black ink in a small squeeze bottle and a portable Chinese brush. So I'm liking just black and white for now. And I love the satisfying feel of drawing with a dip pen. Not as convenient as a fountain pen, but there is something really enjoyable about using a dip nib.
The weird caped person pic was done with a Twsbi fountain pen with blacks added in using the Chinese brush.
