My garage is full of "stuff" so I made myself a Geodesic Dome devoted to Tear Drop creation. And I don't have to clean it up Xcept once a year. It's solar heated and cold in the gray Seattle winter. Desert Domes (shift 2) com is my source for dome info. I use 3" schedule 40 PVC for the hubs, 2x2 for the struts and lag screws from the inside of the hub into the angled ends of the 2x2s. I have a special snow top for the center and 10" of the white stuff, last winter, did not even phase the dome. I can hang from anywhere on the frame
