Gather a square sheet of paper
Fold the paper in half diagonally to make a triangle
Fold the triangle in half again
Fold the paper into thirds or quarters to form a narrow wedge
Trim the top edge if needed to make a neat point
Cut small shapes, curves, or notches along the folded edges
Avoid cutting all the way through the folded point
Unfold the paper carefully
Flatten the snowflake gently
Repeat with different cuts for different patterns
