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
Sandpaper (220 grit or higher)
Step 1: Transfer Design
Make a template out of paper (copy paper).
Trace onto the cardbroad using a pencil.
Step 2: Cut Outs and Dry Fit
Do a dry assembly to ensure fit.
If needed, use sandpaper to clean/smooth the edges.
Step 3: Painting the Snowflakes
Spray a white/primer undercoat using Krylon.
***To avoid having the smaller cardboard pieces from blowing around when applying the spraypaint use any extra cardboard to create an "X-Frame" to hold the smaller pieces in place.
Spray Krylon colors of your choice (the cardboard will take about 4-5 coats of paint for good coverage).
Let dry before handling (this will take a few hours).
Step 4: Final Assembly
Use hot glue gun where (if) needed.
Tie string around one end.
