I am wanting to put fondant draping on a buttercream cake. Is this possible, or will the weight of the drapes cause them to slide off the buttercream? If I roll them really thin, use a 50/50 mix of gumpaste and fondant, and use a good adhesive, will I be able to achieve this without having to use a non edible support (skewers) to attatch the draping to the cake?

I've never tried this, but my instinct tells me that it would be a problem. No matter how thin you roll the fondant, it will do a number on your lovely buttercream finish, because even thin fondant is rather weighty. And, of course, as you say, slippage would probably be a problem, too, because no matter what kind of glue you use, you're still trying to glue the fondant to something relatively soft. Anybody else ever tried this?

I used drapes on on a buttercream cake. It was my first wedding cake. If you look in my pics, it was the 5 tier white w/black bands and Gerber daisies. I don't know if that is the style drape you want or not. The drapes were with Jennifer Dontz's chocolate fondant. It rolls out VERY thin so it doesn't weigh as much. Also, the drapes were only long enough to go tier to tier. I didn't have much trouble and only used water and icing to attache to the buttercream and hid the "connection" with the daisies. If this is the style you are looking for and have questions, please feel free to pm me. HTH

Wow, inspiredbymom, my hat's off to you. I would never have thought it possible to do that, but your cake is lovely!

Thank you Marianna46! I had lots of advice from Jennifer Dontz and help from my DH to put this one together. I guess I also have to say that it is Sugarshacks icing too. That stuff is amazing to work with. I only change the flavoring.

If you search "drape" in the gallery sections, you'll see quite a few people who have put them on buttercream cakes. So I think you just have to be very delicate and wait until your buttercream has crusted.
