I don't know if others use them, but I think those little brass eyelets really help maintain the tension. A bag of 500 is only a couple of bucks. Drive them in with a small punch. I like Idee's idea of only using two holes, I typically put the spool on a screwdriver, thread wire through holes, starting at one end and going to the other (ie, back and forth, top to bottom), drive a nail and end and tie off, then work back with pliers tensioning each row to starting point, drive a nail and twist off. It takes a couple of minutes total per frame, if I cut down to two wires, it would be under a minute...
