I think it was actually called sunshade cloth. Mine was blue and has a tight weave. I can't find the particulars of it, but it wasn't that cheap. After I bought it, I found a boat upholstery shop that not only offered to sell me a small quantity and even to sew it for me. My Singer sewed it just fine... but I did have a walking foot. The hardest part was getting the foot to go over the bungee loops, but that wasn't too bad. I need to make some more. FWIW, I got the idea from the shark tooth collecting bags you can buy from the Scuba stores in Venice Beach, Fl.This sounds like a great DIY project asking:
Where do you buy the sun cloth? Does it dry quickly? Can a regular sewing machine sew it, or does it need an industrial machine, needle? Does it need a particular thread? Any other advice? Thanks!
