Your first wedding cake and you tackled a 'gravity-defying' design like this!?  Wow!  I'm impressed!  :D 

It was done with a stand system that is hidden by the cake.

Wow.  Congrats on your first wedding cake and congrats on being smart enough to choose an impressive stand.  What a lovely first wedding cake!!

Thank you for the comments.  I had a lot of help with the stand.
