How to do Temari ball?
Dividing and marking the ball could be an interesting lesson in three-dimensional geometry – but the ancient masters have made it quite simple. By using a thin strip of paper that is initially pinned to an arbitrary spot on the ball that becomes the “North pole point”, and then successively wrapping around the diameter of the ball in all directions from the pole point, the average – and very accurate – circumference is determined. The strip is then trimmed to this length. By folding it in half, and laying it around the ball, another pin is placed at the fold mark and identifies the accurate opposite “South pole point”. By folding the strip in quarters, and again laying it against the ball the equator, or Obi, line is marked with pins. The strip is then removed while carefully repositioning a pin at the North pole point. It is then folded in however many sections the pattern requires – thirds/sixths, quarters/eighths (etc.), fifths/tenths (etc.) – and laid along the ball aside the pins
