I had glittery snowflakes, styrofoam snowflakes, cotton balls, and these big 3-dimensional snowflakes I made hanging on fishing line from a wire. The shadows on the wall really added to the effect. I learned about those snowflakes several years ago. I taught my 3rd and 4th graders how to make them and we had them hanging in our classroom from the ceiling. They are big and so pretty. I just used regular copy paper.
There were lots of cute snowmen all over the place, but these cookies won the prize in my book.
