I am making my son a dinosaur cake for this weekend, he wants a waterfall on it. I have NO idea how to even attempt this, any help would be awsome!
I want it to be in either buttercream or fondant, I don't like piping gel that much.

Pictures would help also!

Good luck!

One of the posters for that cake said that maybe she airbrushed the color on that waterfall. My first thought was Luster dust... just a bit heavier in some areas. I love piping gel for a water effect, but dont like the taste much. That is a beautiful cake and a great example to go by. Good luck!!

I made a buttercream waterfall on my Diego Safari cake...all i did was just use a store bought tube of blue piping gel took a damp brush to blend it in...I know you said that you don't like piping gel but it made my job alot easier. HTH!
