After further consideration of my post, I have come to the best solution:
Just fold that sooon beeech up into as many little pieces as you can, being sure to crease the edge very sharply with a paint roller, and then wedge it into a little box and then ship it that way.
Or....
Just take the sail apart at all the seams and send it back...
Or...
Just cut it up into small squares and then send it back. They can do the changes to the little pieces and then you just duct tape it back together when it gets back to you-sure to be competitive!
