so i will admit I wasn't the biggest fan of drawing on windows with that being said I did have them choose a small area of window to draw on . markers were a little lighter pigmented but still obviously visable . be helpful if the stencils were sticky other wise they slide. I instead had them use it on a mirror and was much easier . could lay the mirror flat and do it :)
