I have been asked recently to make a wedding cake for a friend. She really likes this cake she found, But does not want the cake covered in fondant. I was looking more closely at the cake she chose, and I am not sure if it can be accomplished.
I am afraid the weight of the butterflies will rip down the side of the cake.
What if you wired all the butterflies together so they could virtually stand on their own? Then just insert a few supports ever so many inches up the side of the cake connecting the butterflies to the actual cake. I'm not an expert, but I definitely think this could be done with buttercream!
I agree w/Cindy if you use a sturdy wire and build from the bottom - in sections; maybe 4 sections so the wire holding the butterflies would rest on the cake board, the only purpose then in attaching them to the cake would be to keep them from flying out away from the cake, not really to support the section. Good luck, it's a pretty cake.
Depends on the weight of your butterflies. I put decor on buttercream cakes all the time --I don't cover with fondant--and have no problem. Just adhere with royal icing or even more buttercream and it should be fine.
