Conductive fabric is available from Amazon. It make an excellent ground plane in place of long copper wires. Several hams in the area have used this with Wolf River Antennas with great result. It's very light weight and flexible. It does tend to get blown about in windy conditions but following are a couple of solutions for that if rocks are not handy to hold it down
Solution 1 - Grommets
I found the cloth is so thin the grommets pulled out. So my XYL sewed in these upholstery reinforcements and I redid the grommets. I use fishing weights on carbineers to hold the cloth on the ground. Very fast setup and flattens out my SWR across the bands with my WRC and 17' whip. de KJ8MRH
Solution 2 - Bias Tape Edging
I had my wife sew bias tape along the edges. She cut the tape several inches longer than the cloth then folded it back and stitched it to form a loop that could be used with stakes.
