I wanted to get some sound advice. I have a client who would like to purchase 3 round cakes from me with camouflage ribbon around the bottom of each. She is then going to transport them out of state and would like to set up and stack the cakes herself. The thing is, she wants to use real shotgun shells as pillars in between each layer. Would that even work? Are shotgun shells sturdy enough to hold up the weight of the cakes? All though I have been taught how to properly stack a tiered pillar cake I have never had one purchased from me until now. I am just not quite sure what to tell this client of mine. Any thoughts you all may have concerning this issue would be greatly appreciated! Thanks!
