This one is super-duper easy. Cute pre-cut snowflakes are usually easy to find this time of year. Alternatively, you could cut them out yourself, of course. That would be a good craft to do in class one day if you wanted to get the kids involved in the project.
The rest is just pre-cut letters, white art paper, and tape. My snowflakes came in a package of 32. Since the door only held half that, I scattered the rest throughout the classroom. It gave it a nice fun feel in there. I free handed the piled snow on the art paper and cut it out. And that's it. It took longer to punch out the pre-cut letters than it did to tape everything up. Easy, easy, easy.
