CAKE STACKING HELP!!!!

Without seeing the designs of each I have no idea if it will look weird.  You will be the best judge of that.  I would dowel it if you stack it - otherwise your 6" cake could possibly - sink or crush your bottom cake.  Especially if you are travelling with it.  Either way - dowel supports should be used in my opinion.  Good luck!

It will hold the cake if you have support under it.  You need to use dowels, straws or bubble straws. I would recommend the SPS system if you have time to order it.

I can't say how the cakes will look together since I can't "see" them.  What will they look like?

I think it will be obvious that they are different.  Besides the texture being different, most likely the whites won't match either.  I am not saying, not to do it.  What is this cake for?

Not sure if any of them are in these galleries now that I think of it. They're here though. John Deere one, rosettes (not well done rosettes, might I add...grrrrr) and sugar gems..might be a couple others.

I recently did a purple fondant cake with a white buttercream cake stacked on top.
 

The question has already been answered.. just want to say if anyone didn't click on AZ's photos, do! You're in for a treat
 

I was the only one fishing for lookers! I'd just never seen your pics all together like that and wanted to share.
