AI have a large light fixture piece that I pressed into fondant. I also have a 16" x4" round cake covered in just smooth fondant. I want to cut a rectangle out 3" high with the light fixture pattern and wrap around my cake. Each time i try to affix the pattern around my cake I either stretch out the fondant and ruin the pattern or I end up smoothing out the pattern when trying to affix it to the smooth fondant. Does anyone have hints on how to do this the right way. I have 5 tiers to cover and its been a disaster so far. I need it consistent as its for a wedding. Thank you.

I would use wax paper, very lightly grease it with shortening, and lay the pattern out on it. Mist the back with water, or whatever you plan to use to attach it to the fondant cake.

Then you just pick up the whole thing, place it against the cake, and peel off the wax paper.

I'm rotten at explaining, but you can google 'wax paper fondant transfer', or jessicakes has a good one. http://jessicakesblog.blogspot.com/2012/04/chevron-inspired-safari-themed-baby.html
