I am really stumped. I'm making a cake for a friend who is into native american healing/culture. I want to centre the cake around this theme, but am having a hard time...
I was thinking of using this medicine wheel as the cake, then adding in some feathers and a colourflow eagle on the top...but I can't figure out how I would do 4 different colours on the cake, this would be the top view, and would continue down the sides...I want to use buttercream, and my recipe is not a crusting BC...any ideas??

If you are going to keep the black outline then I would just divide the cake into the four pie shapes using a small round tip and a piping bag,

Once you have the sections divided then just fill in the colors you want .

HTH

You can apply the different colors using a star tip in a huge zigzag then smooth it or leave, which ever you think looks better.

Smooth using an off-set spatula.

Thanks! I'm just worried about keeping the lines crisp between each section. Maybe if I do one at a time, and refrigerate in between, the lines will stay neat....

Yeah, I understand that. But this would be one of things that I would tell them, it's fondant or nothing. 5 minutes to trace and cut a perfect fondant/GP panel (maybe not 5 minutes)versus possibly a couple of hours of smoothing, chilling, piping very carefully......eh, no thanks.

Besides, you can peel a panel off the top and toss it before cutting.

do you have an airbrush?? You could use pie shaped triangular pieces and remove one at a time and spray with an airbrush. That's what I would do, I hate mixing all those colors of icing! lol

Or... you could make the panels out of colored modeling chocolate and it would taste better.

See?? This is why I post on here! LOL! Yes, I do have an airbrush, and how weird am I that I didn't even think of it! Modelling chocolate sounds yummy too!!!

If I airbrush it, I would, of course, use pie shapes to get the colour sectioned off....but here's my next question. If i put a piece of pie shaped paper over the airbrushed colour, will the colour not come off onto the paper?

Osiyo!
Don't know if you make your cake yet, but I would diffinatly use modeling chocolate for the four directions. MC is also great for figures too. You could make the feathers out of fondant so you can paint them

good luck

Do y'all use modelling chocolate that you make yourself, or do you buy it?? I tried a recipe from here, but found that for figures, it was sort of a pain...could I roll it out like fondant?

I've only ever used modeling chocolate 2 times, but I loved it!! It tastes good and, yes, it rolls like fondant. I used it for the argyle pattern on my golf cake and for the lacy cutouts on my heart-shaped cake. I made it with Wilton candy melts, and it was very easy!
