Sailrite used to sell "kits" for biminis. I don't know if they still do, though. The rails shipped in 3 pieces that all you had to do is cut 2 to height, then a MIDDLE SPAN PIECE YOU'D CUT TO WIDTH. There's more to it than that, but it is too much to recite here. You'd have to have someone to sew the fabric with a heavy thread (192) or the bigger one. I made mine, but not with the Sailrite kit, as I had plenaty of scraps sitting around. It was alot cheaper than the $5200 for the OEM bimini/dodger/filler.
