Make Cut Out Snowflakes Day is observed on December 27, 2018. The snowflake is often a traditional seasonal image or motif used around the Christmas period, especially in Europe and the United States. It represents the traditional White Christmas. During this period it is quite popular to make paper snowflakes by folding a piece of paper several times, cutting out a pattern with scissors and then unfolding it.
A snowflake is either a single ice crystal or an aggregation of ice crystals which falls through the Earth's atmosphere. They begin as snow crystals which develop when microscopic supercooled cloud droplets freeze. Snowflakes come in a variety of sizes and shapes. Complex shapes emerge as the flake moves through differing temperature and humidity regimes, such that individual snowflakes are nearly unique in structure. (With material from: Wikipedia)
