Two persons, facing each other, hold the flag waist high
and horizontally between them.
The lower striped section is folded, lengthwise, over the
blue field. Hold bottom to top and edges together securely.
Fold the flag again, lengthwise, folded edge to open edge.
A triangular fold is started along the length of the flag,
from the end to the heading by bringing the striped corner of the folded
edge to meet the open edge.
The outer point is turned inward parallel with the open edge,
forming a second triangle.
Repeat the triangular folding until the entire length of
the flag is folded.
When the flag is completely folded, only the triangular blue
field should be visible.
