The most crucial and perhaps the trickiest step in making a paper snowflake is dividing the triangle into three equal sections. The most accurate way to do this is to use a protractor to divide the angle at the triangle's apex (the corner opposite the longest side) into three sections, each with a 30-degree angle. If you don't have a protractor, you can estimate the size of the sections as you do Steps 5 and 6.
While keeping the wedge folded, cut out random shapes out of the edges.
