I have seen many beautiful cakes posted on this site that are covered in fondant with a nice fondant ribbon around the bottom. Since these tend to be stacked cakes, I am assuming there is a cake board underneath each layer in the same size as the cake (i.e. 8 inch cake on an 8 inch cake board). The question I have is how is this done if the cake board is a tiny bit larger than the cake? I currently have a 6 inch cake on a 6 inch board but it seems there is a tiny bit of board not quite under the cake even though it is technically the same size. Do you just wrap the ribbon around the bottom of the cake as best you can, making sure it is against the cake and not the sneaky board? Thanks!

Use the board as a guide for the icing, making sure you ice/fondant all the way out to the board. Does that make sense?

You need to cut your board to fit the cake exactly with no overhang. Then, cover the board as if it was part of the cake.

Thanks!

The space between the edge of the cake and the edge of the board is where the icing goes.
