Is it possible to adhere a fondant/gum paste belt to a butter cream cake??? Will it be too heavy to hold itself up?  I have no idea how to go about this.

The one in the photo looks like a REAL belt attatched to butter cream. I don't understand  how this was attatched to the buttercream without messing it up unless maybe they chilled the cake well. 

If I can't figure this out I will have to rest the belt on the cake board which will not look as nice as the cake in the pic. Thanks in advance for any suggestions. 

AYep, it's not any different than a fondant stripe attached to bc. I can do it, over SMBC. I make sure the cake is very cold, and it sticks fine. Need to use judgement of course, can't be too heavy.

Thank you, AZCouture. I thought I would need tooth picks or something to hold it up somehow.

make sure the fondant is not too thick because if it is, it will not attach well and may slide down the cake.

AWill the fondant get soft if left sitting on the buttercream too long?

AI always mix a bit of tylose powder or gumpaste into the fondant if I do make something like that, just to keep it from stretching or warping when I put it on. It shouldn't get soft or gooey unless you cut off air to the cake by putting it in a container that traps moisture around the cake.

AI was just wondering because I made cupcakes with smbc and put fondant mixed with gumpaste flowers on it and after a few hours the flowers were soft.

Beautiful cake.  What are the eyelets made from?
