Fold the paper in half diagonally to make a triangle.
Now, fold the triangle in half so the pointy corners meet.
Fold your triangle in thirds. You may need to adjust these folds a little to get the sides to match up, so don't crease the paper until the folds are just right.
Cut across the bottom of your paper so it is straight.
Cut your folded paper so it looks like the triangle above.
Then unfold it gently. Don't worry if your snowflake isn't exact: No two snowflakes are ever alike.
Square white paper
Delight in one of the most beautiful snowfalls imaginable. Paper snowflakes hovering in midair are the answer to your children's wishes for a snowy day. Kids can happily occupy themselves cutting out dozens of paper snowflakes. Then adults can step in with thread and tape, and together you can watch your family's own gentle blizzard materialize.
