As promised. Thanks again to everyone here for the help.
Ridgeline is 144", width at the corners is 106", so it's just a bit bigger than a MacCat Deluxe. Weight without line is 14 oz. With plenty of 550, it's 17 oz.
Corners are reinforced with two layers of 1.1 ripstop DWR. Reinforcement patches were sewn on, then the hems were rolled over twice, sewn, and then the grosgrain (7/8") was attached. Tie-outs are 1" Speer webbing (couldn't find any 3/4" D-rings) sewn onto both sides of the corners.
Not quite MacCat slick, but I'm very happy with the result. Thanks again to everyone for the help. I highly recommend the project.
