Sharpie all over a brand new book of stamps ( the sharpies were hidden in the desk, she somehow found them)
green washable marker on the carpet
Lucky for us that carpet has just weeks to live or months at most so I don't really care how gross it gets. And the washable stuff washes off pretty easy. The sharpie not so much... I know the easiest solution is to just put the markers out of her reach but Keira and Israel spend hours writing and coloring so no matter how much I put the markers out of her reach they always end up back on the art table within minutes. And Nairi herself constantly asks to color so I don't really want to stifle their creativity....
