Fold a square piece of paper in half diagonally
Fold it in half diagonally again to make a triangle
Fold the triangle into thirds or in half to make a narrow wedge
Trim the top edge to make it even
Cut small shapes along the folded edges
Cut notches, triangles, or curves for a snowflake pattern
Keep some parts connected so the snowflake does not fall apart
Unfold the paper carefully
Flatten the snowflake with your hands or a book
