I've been loving the effect I've seen on wedding cakes recently where it looks like the fondant has embossing that is slightly above the base fondant but close enough that I wonder if the design is applied separately. I'm guessing either that or outlines are being drawn on the base fondant then the shapes are filled in to give the illusion of 3D. Does anyone have any idea? Below is the most well-known example of this effect I've seen. Thanks!!
