India ink is fun stuff to play with. I spilled a little onto some bristol board a few days ago and started spreading it out so that it wouldn't drip. It began to look interesting so of course I spilled a little more and started scribbling in different directions. Before too long a new vector pack was born from this little mishap. Sometimes the best stuff is found by accident . I love having stuff like this on hand. They're great for adding some background texture and interest to your vector artwork.
