I'm going to be doing a bridal fair shortly and am looking to keep things simple and do the display cake(s) in foam rather than actual cake for once. However, I'm having a bit of a trial finding appropriately sized foam. Michael's failed and www.univfoam.com requires a $250 minimum order, I'm running out of time and luck. Any clues as to where I can try to look or order online? Should I just give in and make the darn thing? I’d flip my pans and use them, but I want more height per layer than that. Appreciate the help!
