Any advice would be great. Doing a corset cake this weekend and not sure if I should carve from a sheet cake or use a heart pan with another pan? for bottom. If carved does anyone have a good template for this? Thanks in advance for any help! I'm stuck on this one.

I use a heart pan and then carve a little off the sides of the heart for a more hourglass silhouette.

I carved from a sheet cake and it turned out well. I don't have a template I can send you though. I drew out an outline on a sheet of wax paper, folded it lengthwise in half and trimmed the template as needed to keep things symmetrical, then laid it over the cake and trimmed away. Hope that helps!
