1. Fold the corner of a regular sheet of paper to the edge to square it off. Make sure you make your folds and corners as crisp and accurate as possible on all folds.

2. cut off excess

3. Fold in half

4. Fold into thirds along the long side of the triangle (coming out from the corner pointed down in previous picture. Try to get it as equal as possible.

5. Cut off excess along short end of the triangle. From here you would make cuts along all edges to make empty spaces in the snowflake (make sure to leave paper connecting both sides in enough places to keep the whole thing together.
Unfolded it looks like this (maybe it's 12 sides instead of 6?)
