How to Fold a Snowflake
To fold a 4-point snowflake, start by getting a square piece of paper and folding it in half twice to make a small square. Next, rotate your square so it looks like a diamond, with the bottom point closest to you. Then, fold your diamond vertically along the middle. Finally, cut shapes out of the edges of the triangle to make your design, and carefully unfold it to see your snowflake.
Use a square piece of paper. If your paper is a rectangle, simply fold one corner across the paper so that two of the sides match up. There will be an extra rectangular flap that isn't part of the triangle that this creates. Cut this flap off and unfold the triangle. Fold your paper in half twice to make a small square. Fold it once lengthwise and once widthwise, in either order, to make a small square. Rotate your square. You want it to look like a diamond to you with the bottom point closest to you. Fold your diamond vertically along the middle. To do this, simply take the point on the right and fold it over to match up with the point on the left. Cut the edges. Cut shapes out of this triangle. Cut small shapes out of the edges to make intricate designs in your snowflake. Unfold your snowflake. Carefully unfold your paper to reveal your 4-point snowflake. It may not lay flat, so stick it, unfolded, into a book or in a stack of magazines for a couple of hours. Once it lays flat naturally, hang your snowflake in your window or around the house. Begin with square paper. A good size to start with is an 8.5”x11” piece of paper. Cut the paper in half—making the cut across the width rather than the length. Now from these two pieces, you want to cut squares. This will give you snowflakes that are 5” across. To make a perfect square, simply fold one corner across the paper so that one of the sides lines up perfectly into an isosceles triangle. Trim the excess paper. Make a small triangle. Take your square and fold the bottom right corner to the top left corner to make a large triangle. Fold this larger triangle in half to create a smaller triangle. Fold your triangle into thirds. Place the point toward you. Take the top right corner and fold it straight across in the triangle. Instead of folding in half this time, fold it in thirds. Once you fold the right corner over, fold the left corner over as well. Your ending product should look like an upside-down cone with a small triangle missing from the top. If you have a protractor and want to be precise, each third will be a 30 degree angle. Cut your paper into a new triangle. With your paper folded in thirds, cut the top of the paper off at an angle. Do so in a way that all the layers on the top are now even. You'll once again have a smaller triangle than you had before. Begin cutting your snowflake. Cut away shapes from the sides of the paper. Small triangles are easiest to start with, but adding more complex shapes to different parts of your triangle will make for a more interesting snowflake. Feel free to cut the shapes out of the bottom of your cone shape to alter the edge of your snowflake. Cutting the tip off will add a shape in the middle. Carefully unfold the paper. Your snowflake is finished! If you want to make any adjustments after you unfold it, you can. If it's not sitting flat, put in in between the pages of a book or a stack of magazines. Tape them to your windows or hang them around the house to showcase your beautiful 6-point snowflake.
