Sorry I can't get the picture to open, and the link just goes to tiered cakes. Can you try to post it again?
AI'm sorry, are you asking about the whole cake or a button tier? Which one is the button tier? The top tier?
I presume you mean the bottom tier. If you go to the tutorial section you should be able to find out how to do this as there was a tutorial posted on it some time in the last couple of months.
Yes, I meant Bottom. lol
I searched toturials and couldn't find.
Can someone help further.
I believe it looks like a small or medium size circle cut in half and placed accordingly. If you use the picture of the cake you can pretty well see how it is done. You could probably use either royal icing to make the connection tight. Hope that makes sense.
oh and of course using fondant with a combination of gum paste, which is optional.
