Traditional fondant cakes have a rounded edge at the top of the tiers, but when more wedding magazines started showing photos of cake dummies with fondant on them, the edges started looking more square, as is the nature of using fondant on styrofoam.
The more square edges have made their way onto real cakes, and for a lot of decorators the goal of a really sharp edge has come to symbolize a cake that has the fondant done the right way. Rounded edges aren't the goal anymore.
I personally like the way that a sharper edge looks, and I try to get the edges of my fondant cakes fairly sharp, but I'm starting to second-guess that a little.
Pearls or piped borders? White or red roses? Rounded or sharp edges? I think that it's becoming something that needs to be addressed, since it seems that people are starting to have a preference, and it does affect the look of the cake.
So what do you prefer? Is this something that should just be considered part of each decorator's individual style? If you like doing rounded edges would you do sharp ones if specifically asked to do them, or vice-versa?
