How to Make 6-Sided Kirigami Snowflakes

We've all made them. I remember making hundreds of paper snowflakes when I was in elementary school. You take a piece of paper and fold it in half, then fold it in half again. You now have a piece that is one fourth the size of the original. Now you fold it in half diagonally. You then cut slices out of the edges of the paper, and unfold to find that you have created a snowflake. The resulting snowflake has four lines of symmetry and looks something like this:

If you fold it in half diagonally again before cutting, you can create eight lines of symmetry and have a snowflake that looks something like this:

While both of the snowflakes above are pretty and symmetrical, my inner scientist isn't happy that they don't have the six-sided symmetry of a real snowflake. Since water crystals form in hexagonal layers, many snowflakes have a hexagonal symmetry. There are many lovely pictures of real snowflakes, as well as some interesting information at SnowCrystals.com, taken by Kenneth G. Libbrecht, a physics professor at Caltech. Here are just a few of them:

There are ways to fold paper to make six-sided Kirigami snowflakes as well. Here are pictures of a few snowflakes that my wife and I made last night.

If you decide to get fancy you can even make recognizable designs as long as the designs have one line of symmetry.

Tools & Materials

square pieces of paper (origami paper or make your own squares)
cutting device (scissors work, but an X-acto knife is so much better)
folding instructions

How to Make Square Paper

All of the instructions below assume square paper is being used. If you need to make square paper, here is a fast way to do it.

Take an ordinary piece of paper and fold it diagonally. Cut off the remaining strip.

Unfold your square piece of paper.

The square created above is 8.5 inches on a side. If you want smaller paper, fold in half vertically, and then horizontally. This makes crease marks that I cut along to make four square sheets that are 4.25 inches on a side.

Read and followthese instructions. Start with a square piece of paper.

Fold in half.

Fold in half the other direction.

Unfold the last fold and then take a corner of the piece of paper and fold down so that you have a fold running from the center of the piece of paper to where the corner touches the last crease that was created. This will form a 30-60-90 right triangle because the longest side is twice as long as the shortest side. (If you remember some of your high school trigonometry)

Note: the corner you pick actually matters. It must be the corner that has a fold in the paper—not the corner where two edges come together. If you pick the wrong corner, you will end up with two half snowflakes and would have to tape them together at the end.

Now fold the other corner down to meet this side that was formed.

Cut off the end. The angle you choose decides the outside shape of the snowflake.

You can create any shape that has a line of symmetry.
