This is how the snowflakes look like at night.
You can find the printable templates I used here. You may need to enlarge the pattern.
If you google snowflake templates there are lots of different templates to choose from. When using these templates you cut out the gray area after it is folded into a small triangle.
First, you start with a hexagon.
I don't use the pattern with the lines anymore but it is helpful the first time you try it.
Then, you fold the hexagon in 1/2
Fold in 1/2 again
Fold triangle 2 more times and then draw on your template(if you are not using the gray one).
Cut it out
Then you have your snowflake!
This is how they look during the day (yep, no snow outside).
