This arrangement is elevated 4" by a styrofoam round; two 8" round are pushed slightly under the 'main' cake consisting of 16, 12, 8, and 6" tiers. All are buttercream. Roses are air-dried buttercream. This was set up around 9 a.m. for a 6 pm wedding - the only way I could fit in the delivery of all 4 cakes that day. I never got any of my equipment back :(
