The zip ties will get old fast and break. If you can, the best option would be to just add a 2x4 to that spot that you have the seam and fasten it with some galv or coated screws with some fender washers. But I don't know what your coop/run looks like and if that is an option, but if not the wire that came with the hardwire cloth wrapped around it could be used to "stitch" the two pieces together or you can buy a bag of metal chain link fencing fasteners at Home Depot or Lowes and try that, I know they sell a special pair of pliers that make them easier to attach, but you might just be able to use regular pliers instead.
