Just wondering if anyone has some advice for me regarding a tiered rosette cake. I want to make the cake pictured below but I am wondering how to stack it. I have stacked a 'smooth' cake before but the rosette cake uses a ton of icing so I thought maybe I should get some advice first before tackling it. Should I:
1. Decorate both cakes and then stack them
2. Crumb coat, stack and then decorate.
Also wondering if anyone knows of a good video tutorial on making buttercream hydrangeas like on the top tier of this cake? I have only been able to find tutorials using gum paste.
Any advice anyone is able to give me would be greatly appreciated.
