I need to do a peacock sheetcake or square cake, not layered. Has anyone done a FBCT of one? I have an image, does anyone think this will work?

I thought about a RI raised relief work, but I don't think I could get deep enough colors.

Any advice, please.

I've never tried FBCT but really want to. Seems like it should work. For all images like this, I trace on parchment. Then flip the parchment and go over the outline with tinted piping gel. I then flip the whole thing over onto my cake and the outline (for the most part) is there. Then I outline in black BC and fill in with my colors. A lot of work, I know! Good luck.

FBCT would be the best way to do it. There are FBCT tutorials here on CC do a search to find them
