Yep. Just under 3 hours. I could of finished it faster but I had to make the panels 60" wide since cuben is 54" wide. So rather then have 3 ridgelines, I bonded six 60"x54" panels together which really slowed me down.. As far as the design goes, I did it as I went. There were no drawings, just a 6' straight edge, a 10' tent pole and a few clamps for the cat curves, a razor knife to cut the design, and calculator to make sure everything ended up right..
Here is a photo of the all the bonded lap seams. As you can see there are ALOT..
