This is my very simple device I adapted for the mark making
project. I cut circles out of foam, hot glued raffia and string to them, and attached them to a drill bit. The long raffia needed to be used on a very large surface to get any detail and the short just wasn't interesting. The string made the most variations of marks. Since I couldn't find my extension cord, I used it until the charge gave out. I found that it made different marks according to the speed and the amount of ink. I thought the variances were really versatile.
Below are my five pics:
