I really love those decorations that are the show-stopper of the neighborhood, like this! These window clings and silhouette are very popular for the holidays. But they also can be pretty expensive. But if you have some minimal art skills, you can pull this off, and do it on the cheap, too!
All you need is a few rolls of craft paper, some craft paints, scissors, an exacto knife, clear tape, and a pencil.
You could handle this project several ways, but let's go with the simplest one.... I suggest measure the inside of the window, and cut your craft paper to fit. Then take your pencil and draw a very simple design (it might be a good idea to use a picture as a reference) then cut it out with scissors and/or your handy-dandy exacto knife.
Then place it back in the window to check your measurements, and also check it out from the outside too, to make sure it looks the way you want it to. Then after you're happy with it, take it down and apply the craft paint. Let dry, then put up with clear tape.
Remember, when doing a project like this, the more simple the design, the better it'll look. Keep in mind, you want it to be recognizable from the street, so don't make it too fancy, think simple shapes.
This also is a fun art project for kids of all ages!
