My first Topsy-turvy cake, first time painting with airbrush and metallic colors (bronze, copper and gold) with a touch of art. Tiered stacked construction, Round 8x3, 6x2, and 4x2 in. covered with a Satin Ice rolled Fondant and gum paste accents. The method that I used for making a cake crooked was: to use Styrofoam wedges between normal-shape cake tiers. This way, the wedges make the cake look crooked when stacked, even thought the cakes are straight. Nov / 23 / 2008. Thanks for looking! Gracias!
