How do you paint with acrylic paints on windows?

I was asked to paint some winter scenes on some office windows down town, but I have never done it before. Do you paint on the inside or the outside of the window? What is the best type of paint to use if you want it to wash off, and what is the best type you want to use if you want it to stay on, even after a washing?


Thank you all, in advance.How do you paint with acrylic paints on windows?
Clean the window well,take a grease peccil to draw your design on window,then start to paint.Sometimes it should have a black outline if it is for the holidays.It wuill be seen better from afar.Acrylic can be pealed of glass or something like a acrylic paint remover,(art store or hardware store).So good luck in your creative endeavors.How do you paint with acrylic paints on windows?
I do this all the time first prep, the window with straight gesso.after it dries add another coat, then your ready to paint.
Well. I don`t.
