I forgot we weren’t supposed to do the crown already. I made it using vertex slide. I assume a pole at the top is correct, I don’t know how else to join at the top without it. It would appear my method is a no-no because it makes non-planar geometry.
I also thought it might be nice for people to be able to reference this directly instead of going back through the videos like I did. I need to get a pad of paper to keep close by for writing reference information.
