I used black and gray Uni Posca markers on this large window, just traced designs that I had enlarged and printed out. It will all wash off with rubbing alcohol if I decide to do something else. These are the markers that car dealers use.

I'd like to do a kitchen one too and put today's menu on it! The marker really comes off easily, so it would be ideal.

I blocked out the one word cause it is my last name. :-)
