Get one of those vacuum packing bags(the ones that you hook up to the vacuum cleaner). Large enough to lay the kilt flat. Seal it up, and suck it down locking the kilt in the flat position with the pleats flat. once vacuumed, the kilt is ready to be placed in a box.Bend it if you want , it will not hurt the pleats. The pleats are pressed down until opened by the reciever. Good luck.
