I have seen these 3D paper snowflakes around (mainly the office) and had no idea how they were made until my girl friend shared the recipe, er, simple how-to. I think these would be so pretty in various colours of paper and sizes.
I made the one above and hung it in my office (from the blinds). Next I plan to make several different sizes (likely all in white) and hang them from the ceiling in my front foyer to add some holiday cheer.
