Hi, up to now my cakes have been small enough that bubble tea straws have sufficed but I have a 5 tier wedding cake to do next month and I’m sure the straws just won’t cut it. Should I use wood dowels or poly dowels or would you suggest I use a support system like sps or something – which I’m not familiar with at all. The cake is going to be 12", double barrel 10", 8" 6" rounds. Thanks for your help! Any advise would be appreciated.
