Hi Leghorn. About 10 years ago we bought black cord knotted mesh from a rather up-market on-line garden equipment place. They sell all sorts of 'twee' stuff but the mesh had 1/2" holes in it and was remarkably strong, although expensive. Only trouble the rabbits ate through it and it will have to be mended before we can use it again! They sold the stuff to cover their fruit cages -Harrods Horticultural I think it was called. We Obtained a small polytunnel frame and erected it over our sweetcorn then threw the mesh over it and pegged it down with poly cord threaded along the 4 edges and pulled tight. The piece was about 5 metres square and was £80 then.
