Lol, thanks so much for the compliment it was a scary endeavor! I made the cones by slicing just the bottom edges off off the cones and scoring the inside support of the cone and I kind of worked them out as gently as possible. Once I had those ready (8 good ones) I took two sets of the 2 1/2" globes and used piping gel painted on with a brush to cover the ball and then stretched the fondant gingerly around it trimming around the very bottom. Then I took the 9 1/2" pillar and pushed it through the top of the globe to get a clean edge and then I slowly worked it into the cone and glued the cone to the fondant covered ball with piping gel. And after I got that set up I stood them up on a cake separator plate with the feet facing up. After all 8 dried I trimmed the edges with fondant to make them look like a scoop smushed down on the cone.
For the assembly I marked my cake with the feet of the cake separator and then because I was afraid if just turning the plate and marking it again I measured where my first marks layed from the edge and marked four additional places in between the first four. I trimmed the fondant with a knife so when I poked the pillars in they wouldn't crack it and pushed all eight pillars in place. I let them sit until I assembled the cake at the party.
I did not do any fake cones or fill them with chocolate because the cake I made was a 14, 12, 10 and with the giant cupcake I wanted all the support I could get for that bottom tier. In fact besides my tiers being smaller sizes I went mostly by the book but I do believe it called for 2 sets of the 2 1/2" globe pillars anyway. And my customer was more than happy to return all my equipment because I charge a deposit for them.
Hope this helps, it was a great learning experience for me and I have a great game plan for it on the next go round.
