Does anyone have an idea where I would look for the material used in patio chairs? I wish I knew what it is called, it is not that canvas type material, it is the type of fabric that is not completely solid, it is kind of see through and a rougher type of material. It is torn and I would like to get a little more time out of the chairs before I would have to replace them. Also, any ideas on what woudl be the best way to repair places where the trim covering material on the tables edges is almost just flaking away and it is rusting underneath that material?

Thanks!
