They are actually dow rods "wood" they are tied up on the screen with floral wire I notched the ends of the dow rods with a carpet knife to keep the wire from slipping off.
i just bent some fake fines and use some lightweight fishing wire to hold it up just wrap it around the lil holes in screen and around the vine and double knot it couple times and it works great and you dont gotta poke holes for zip tye's
