Bob,
Maxx of Flex sails can be joined in a number of ways. for a production (ie a sail requiring no more development) sail they can be glued as you describe (which is actually ultrasonicly activated) and do not need stitching, or if you are developing sail shapes and want to alter the seams you simply use venture tape and sew the seams. then its super easy to alter.
