Each row takes one piece of net thrown over the top of the canopy, down both sides to the ground and on by the tuck, and carried over both ends of the row. Canopy size, tuck and clip spacing are yours. The net is counted at the full roll width you enter; spare width hangs further down or is gathered. Clips close the two lower edges under the canopy, or join neighbouring nets, at the spacing given with one at each end. Posts and wires for overhead netting systems are a different layout. **This is a quantity take-off; the mesh size needed depends on the birds you are keeping out.**
