So I was thinking last night this might be fun to try. What if we start a drawing and each person adds one line until the drawing is finally finished and then start over with whoever finishes it? So no colouring, just adding lines. I guess if you like the turnout though you can always colour it!

2. The line can be of any length, can be curved, bent, straight, wavy, etc.
3. The line may overlap other lines and can be any width, but you cannot erase someone else's line.
4. Have fun.
