it looks as though the lighter colors were marbled together and then they combined the marble fondant and brown fondant. moosh a ball of brown and ball of marble varying sizes of balls and roll it out. the colors will flow into each other
I think it looks airbrushed.
It can be done the way Lacey said, but it looks to me as if it were a couple shades of brown swirled together then air brushed green hues. The same for the leaves air brushed it seems. Nice cake, post if you do it.
Are those deer cakes also?
Thanks everyone. The heads will not be cake.
If you mix (knead together) colored fondant and roll it into a log, then fold it onto itself, roll into log again and fold over, etc., you get long streaks of the diff colors when you roll it out. From there it looks like it was simply scored to resemble bark.
