Ok.. I have confused myself! I have a wedding cake due in 3 weeks that I quoted back in January. Keep in mind that when quoting this cake I referred to the 'Wilton Wedding Cake Guide' - 60 serves required for 'tea & coffee' not dessert - square cake with 3 tiers (one centre tier dummy + fruit cake top tier for anniversary). I offered to start at a 12" for the base thinking it would feed 72 as suggested in the Wilton guide.. however, I then stumbled across Earlene's serving guide which suggests a 12" square only feeds 60! 
That means the bride and groom would be 5 serves short! I was thinking of ditching the dummy and making a second tier in a different flavour at my own expense just incase the 12" isn't enough. I could just say I had an order cancelled at the last minute and I don't like to freeze my fresh cakes and didn't wish for it to go to waste?!
Is my first quote correct? Or do I need to ditch the dummy for real cake?
