These window crayons are sooo fun for the kids. My 17 month old even loves to draw on the window with them. I hadnt seen them until we went and spent spring break at my moms and she had gotten then for the grandkids to draw on her windows with.
They work perfect on our big picture window we have in the living room. I just let them have at it and then we wash it off. It comes off really easy with a wet rag OR I just like to use vinegar water and wash the whole window while Iam at it!
I bought them at walmart! Here's the crayola link for more fun with kids:
