Coffee filter snowflakes

SO this is a classic winter activity that I can remember doing as a kid. It is so simple you just take a round coffee filter and fold it in half then in half again and again. then you cut the sides not going all the way through the filter. when you open it looks like a snowflake. We made several and up them up on the siding glass door. She was not very enthusiastic at first then when she opened it and it looked like a snowflake she was so excited and couldn't wait to do more. I think this may be a new tradition.
