I got an order for this amazing cake. Does anyone have any ideas how they did the swirled look to it?

thank you!!!!

It looks like they used a coarse paint brush and dry-brushed food color onto it (probably mixed with vodka or extract).

That's what I thought, too. Does anyone think that the fondant underneath is a very pale blue?

I would probably cover it in the light blue first. Then use a "paint" made from blue luster and vodka, or blue coloring vodka, and luster- however it worked best, and then paint it.

Yeah, I did that once. Coarse bristle brush, like a house paint brush. And you don't have to worry about streaking the paint! Goes fast.

Thanks! The coarse brush sounds perfect.

Iâve applied luster dust to my cakes but not like this!
What is the dry brush tech? How do you do it?
Thanks!

Not a dry brush. You mix up the "paint" as always, maybe a tad thinner and brush it on with a coarse bristle fairly wide brush. Just like faux finishing a wall. In fact, you can sponge on "paint" for various fuax finishes.

Leah S-do you have any suggestions about the color of luster dust/petal dust I would use?

Do you want it to be blue? Then a blue luster. Or paint it first with edible paint (gel color + clear vanilla or other clear medium) and then after that dries go over it with a pearl luster and a soft brush (like a makeup brush.)

She wants it to be aqua/swimming pool blue. Do you think regular blue will be good?
