I used two sources when building my paper geodesic dome:

The YouTube video inspired me to make a dome from paper and gave some tips on how and the diagrams on makezine were brill.
This is a 2V dome. That means there are two different strut lengths. I made them from yellow and white paper so I could see the pattern. One strut length is 88.3% the length of the other.
