This is an easy, easy, easy project and can probably be done for free with things you have lying around your house!!! I used a needle and thread to string cotton balls. After one, two, or three cotton balls I tied a knot and moved down the line. I highly recommend doing this while watching your favorite Christmas movie, because although this is super easy, it does get a bit tedious and boring. But the end result is oh so worth it!!!
I added a couple of snowflakes I had lying around to spice up the window. But you can get lots of different types of snowflakes from the dollar store.
My son loves to walk by the window and point out the snow.
