Henry et Henriette liquid chalk pen would do the trick!
i want these on my window :) or make some other drawings on my window
Beautiful window drawings! Something like this can be done with liquid chalk markers - it dries and won't smear until you wipe it with wet cloth.
Writing on the glass... any book quotes would be fun... in a form like this or just random lines
