I am making a wedding cake with a grape vine strolling down from top to bottom. The vine will be inserted into the center poll and come out from there. The top cake is 6" square and the vine will be laying on that and then bending over to go down the cake. One branch will go between the top and middle tiers and the other will go between the middle and bottom tier. The center vine will flow down the front of the cake. I have attached a picture of the grape vine so that you can see what I am talking about. It's a bit heavy so I was wondering how you would support it so that it doesn't damage the cake. Any help would be greatly appriciated.

For some reason it didn't let me upload the picture. It's in my pics, here is the link.

Will the cake be covered in fondant or BC? If it is fondant, I don't think it would damage the cake.

It will be buttercream.

I know alot of you out there deal with structural issues. So there has got to be some answers. Please help. I really don't want to take my grape vine apart.

Can you attach some picks to the grapevine that will go into the cake. That would keep it from shifting around. Hopefully somebody else that has actually made a cake with a sililar arrangement will comment. I'm sorry I'm not more help.

I was thinking of putting a support post (i.e. a sturdy plastic tube) under the vine as the vine is heavy and I don't want it to sink and teat into the cake. Just wondering if there are any other suggestions out there.
