Seabags.com They recycle your old sails. I called them and within a couple weeks, somebody picked up my old main. They give you a free bag and use the rest for their rapidly growing biz. I wish I was aware of them when I built a genoa a few years back. That went in the landfill as I couldn't find a good source. They need a lot of old sails to keep up.
