I am a cake decorator, and the cake embryos made in the store are basically Qifeng embryos. 12 inch 10 inch 6 inch are 4 kg, 3 kg and 1 kg respectively. This combination is more common, and it will not collapse when making three-layer cakes. The cake you make is small because the height of Qifeng embryo is not enough, and the first layer of cake embryo is 7cm after sandwich, so animal cream is not easy to send away.
