Step-by-step diagrams

Steps 1–7

  1. 1

    Fold the square in half

    Bring the bottom edge to the top edge. The midpoint of the folded edge is the snowflake centre; mark it lightly.

  2. 2

    Fold the left third across

    At the marked midpoint, use the 60° corner of a set square to mark a ray up and left. Fold the left side over that ray; its folded edge now points up and right.

  3. 3

    Fold the right third across

    Fold the right side over the matching 60° ray up and right. Line its folded edge up with the left sloping edge. All three sectors should match at the centre.

  4. 4

    Halve the wedge

    Bring the left sloping edge to the right sloping edge. Fold straight up from the centre to make a narrow 30° packet with twelve layers near its point.

  5. 5

    Trim the uneven tips

    Cut straight across the packet 48 mm above its centre. The two uneven ears fall away and every sector now ends in the same straight edge.

  6. 6

    Cut the star points

    Start on the straight folded edge 26 mm above the centre. Cut one straight line out to the far corner of the sloping edge. The long wedge that falls away leaves a sharp point.

  7. 7

    Cut the diamond window

    Cut a narrow triangle into the sloping folded edge, 30 mm from the centre. Stop 3.5 mm from the edge and cut back out to the edge 14 mm farther along.

Steps 8–12

  1. 8

    Cut the small gap

    Cut a small triangle into the straight folded edge, between 12 and 22 mm from the centre. Leave the paper beside the centre whole.

  2. 9

    Open wedge half

    Open this crease gently, leaving the earlier folds closed. Keep the uncut joins together.

  3. 10

    Open right third

    Open this crease gently, leaving the earlier folds closed. Keep the uncut joins together.

  4. 11

    Open left third

    Open this crease gently, leaving the earlier folds closed. Keep the uncut joins together.

  5. 12

    Open half

    Open this crease gently, leaving the earlier folds closed. Keep the uncut joins together.

  6. ✓

    Finish

    Ease the creases flat. Lift the opened paper by an uncut edge to see the whole pattern. Hold the opened paper upright and flat, with the whole pattern.
