Yeah, I can see from the picture very well how yours are made. Nice!
I think that at this point I can probably summarize the arguments for and against folding and sewing as follows:
ADVANTAGES: Looks a bit neater (provided that a good sewing job is done); more strength for pulling on snap when need to unsnap; makes the screen less prone to being stretched out of shape.
DISADVANTAGES: More work; uses more material; looks tacky if poor folding/sewing job.
