Step 3- Cut

Step 4: Step 3- Cut

Alright, the moment of truth has come. Go slow and be careful. I've ruined too many flakes accidentally cutting to far, amputating a part of the snowflake.

Helpful cutting hints:

Cut out the tricky parts first. Make a bit of a mental plan how you're going to go about it. You may find it helpful to number each part in the order you will cut them out. (See photo)
Leave parts attached to hold on to. The cutting gets harder as you go along because you have less and less to hold on to as you cut bits off. Doing all the cuts but a cut in from the edge will leave you sometihng to hold on to but also be easy to finish. (See the photo with notes on the robo crotch)
Go slow and be careful. Yeah, I already said that, but it's worth repeating.

Carefully unfold and enjoy! You are done. I bet you ended up with a pretty sweet snowflake! Feel free to post it up on flickr or Google+.

Have a wonderful Christmas!
