I have a mojor dilemma. I am doing a cake next week that is 7 tiers top 6 are round and the bottom is square. They were very picky about the color, white but not stark white, but not ivory. So I said ok......Antique white with bright white gumpaste flowers. They just decide on the final designs last week. Not a problem, only I cant order this color and get it here before next week. And the cake store I shop at doesnt have the color, only the pearl dust, and not enough to cover the cake. Any body know how to achieve this color? It has to be perfect, the cake and wedding will be featured in Houston Bridal magazine!!!!! Please Help!
