Got a request this morning to do cupcakes for a wedding (100 of them) that must be stacked with a small (I take a 4-5inch) cake on the top of all this.
Has anybody done something like this, or got any ideas as to how one would go about doing this?? Suggestions would be greatly appreciated.

Do you mean this style?

ac2steachk - thank you so much for those links, I will print and show this to the mother, they all look good!!

there are links to making your own cupcake tower in the cupcake forum, if you need help.

I found this one on cc and thought it was absolutely beautiful and very elegant.

Thanks everyone for your responses, I have looked at them all

neomommy, thanks, I went and looked at all the different towers that there are and some of them look pretty interesting, so I might just go with something like this. Just can't make up my mind if I should go boards or glass.
