I worked my way down from center, one tier at a time, tacking a small piece of lathing below each hub and pleating where necessary to take up any slack that appeared as it curved down. As long as I didn't try to move down before every attachment at a given level was complete I didn't have too much trouble molding my plastic to the concave surface. I was impressed by how little I needed to overlap this way.

Once I ran out of plastic at the bottom edges, I started at the door and added 10' tall x 20' wide pieces of plastic around the sides until I had worked my way completely around. These were a bit trickier, and I ended up with a few pockets where I couldn't push the plastic out to all of the hubs. I think when I redo the inner plastic I will attempt to attach these bottom pieces near the bottom set of hubs (at ~3' high) first and then pleat upwards.
