Oh dear… budding arists don’t always choose the right surface.
Good news: in most cases, it can be removed!
Here’s what to do:
Alcohol (70% or disinfectant): Soak a clean cloth and gently rub the pen marks.
Wipes or acetone-free nail polish remover: Effective on faux leather (test on a small area first).
Baking soda + water: Make a light paste and rub gently.
