So I was sitting at my drafting table the other day dilegently doodling on my calendar when a stray copic marker came rolling down from the pile of work related items at the top of the table. It came to rest against one of my favorite multi tasking tools. Yep the good old toothbrush. Sooooo, I had to try it. If you take a fairly fresh Copic, one with a good amount of ink in it and start pulling it towards you ( you want to pull it towards you so the things fly away from you ) across the end of the toothbrush bristles it will make a very nice, fine and relativley even ( depending on the condition of the toothbrush ) spray of ink!
Give it a try.
