100 Crocheted Snowflake Patterns - I discovered this amazing directory of snowflake patterns linked from a fantastic blog called Snowcatcher. I seriously recommend checking this out. This woman has mad snowflake-making skills. There are over 100 snowflake patterns on that directory and they are all unique.
Take a styrofoam ball, buttons, and sewing pins. Stick the pins through the holes on the buttons, and then stick the buttons into the styrofoam. Make sure to fill the whole ball with buttons! Have fun!
