What a silly answer ! The production of a flower bouquet from a zombie ball features in the teaching by Jeff McBride in L & L Publishing's dvd 'Secrets of the Zombie Ball'.
Jeff also demonstrates how to handle the Zombie infront of and beside a folard - 'folard-free', as does Jeb Sherrill, in 'Dream Gimmick' and his 'Zombie Re-visited' dvds.
Raymond Crowe does a COMPLETE ROUTINE with NO folard !!!!- see his 'The Naked Zombie Ball'.
Also, this reply is inadequate: the idea that the diameter of the U-Day Ball is "about six inches" is useless to me: I want to use EXACT dimensions when I modify equipment - as do most other magicians !!!
