How to Remove Ink From Furniture

With my kids, it seems like there's always a time when they have to test their limits and artistic skills on things that aren't normally for art. My daughter, age 2, decided to experiment and draw a rather creative drawing in ink on our ottoman. I quickly gave her a time-out and went over and over with her that we only draw on paper. Luckily, I've had previous experience with my son drawing on a window ledge with ink and knew that rubbing alcohol would help. I poured rubbing alcohol on the creative drawing and blotted at the masterpiece until it was gone.

What unusual "masterpieces" from kids have you had to clean-up?
