I have a client requesting her tiers to be floating. I have seen cakes where it looks like each tier is seperated by a block that's covered in fondant to match the cake. Does anyone know how this is done?

pinkcakebox has a bunch of cakes done with this technique in their wedding gallery. some seperators are round and others are square.

"Floating" is the of the style where each cake is on a separate stand, like the Crystal Splendor stand.

i guess i used the wrong terminology. she wants space in between. I think she would go for this. she's looking for more height.

I've also seen this style with square separators.
