I had a few hours to play around so I drew a design on Corel x4 and built the snowflakes out of supplies I already had.
Cutter (Laser Engraver / Utility knife / scissors / razor blades / etc.)
Krylon Spraypaint (white or primer and colors of your choice)
Cardboard sheets (0.108 inch)
Painter spray sheild (can be found at the local paint/hardware store)
Hot glue gun and glue sticks

Make a template out of paper (copy paper).
Trace onto the cardbroad using a pencil.
