Hello everyone! Can anyone out there give me an idea on how much IMBC and fondant I would need for a 12,10, an 6 inch wedding cake? Also do you use 1 3inch layer torted twice (3 layers total) for each tier? Thank you so much for your help

Anyone out there please?????

According to the Satin Ice chart, you'd need 52 ounces, or about 5 pounds. That would be if you're rolling it exactly to specifications. Personally, I would order 10.
I torte each layer of cake, so there are 4 layers of cake and 3 layers of filling. I haven't used IMBC. I used SMBC. But, for that size cake, I would probably make 2 large batches, using 4 cups of eggs whites and 6 cups of butter total. There would be some left, but I just freeze it.
