I'm looking for the best way to hem up no-see-um bug netting?

the only thing I can up with is to take 3/4" flat nylon ribbon and fold it over the edge leaving a 3/8" on either side. just seams like it would add a lot of weight. I also tried pulling the inner threads out of 550 cord and using the sheath to sandwich the netting between the zipper strap and the 550 cord.
