it looks to me like whom ever made this cake used a leaf petal cutter. Cut out all the shapes to make a criss cross pattern, stuck them down. And then covered it with another sheet of fondant to give it a clean look but make it looked raised
Thats pretty impressive! I would love to know how to achieve that effect.
Cut out circles. Lay circles in a perfect straight pattern row on top of row. Put same circle cutter evenly covering the edges four circles. Make sure it is centered over the spot in between those four circles and cut. Move to the next group of four and so on. Discard the cross shape left over from the circle centers and carefully line up your pattern.
I think alene is referring to the layer at the top of the photo, above the flower. It looks like a decoration was put on the layer, then fondant was layered over top to have an indented grid-like look. Alene, is this the layer you are referring to?
The waffle pattern? I'd try a waffle iron, cold of coarse.
I would look up patterned rolling pins.
