Fold a thirty-degree wedge
Start with thin square paper. Fold it diagonally, then fold the two sides into thirds around the midpoint of the long edge. Fold the resulting sixty-degree sector in half once more to create the thirty-degree wedge shown in the PDF. The final wedge opens into twelve mirrored sections around six points.
Match the template to the wedge
Clip a template onto the folded paper with its point at the centre. Remove the grey regions, including the marked notches at the edges. Keep the white connecting sections along both folds intact. Some designs have interior cut-outs that need a careful snip; choose a simpler pattern when those cuts are unsuitable.
Pick a design by difficulty
The six designs start with large simple notches for younger children and finish with narrow slots and small triangles for steadier hands. The small preview next to each template shows the opened snowflake, so you can choose before folding. Copy paper or thin origami paper cuts most cleanly; card stock is too thick once it has been folded into layers.
Display or colour the finished snowflakes
Press the opened snowflakes under a book for an hour before hanging them on a window or a string. The last page has four finished snowflake outlines for colouring, tracing or using as a stencil. If you want more paper-cut shapes for spring, the related paid pack has flower templates in several sizes, a layered set and instructions.
