I am doing a nature cake for a grad going into conservation. I want to make the waterfall the main focal point. I have seen some great waterfalls done by CC members. I was just looking for pointers. I like the look of the white waves over the blue water. I am just not sure how to get it to come down over two different layers and look like flowing water. Any help greatly appreciated

My favorite technique is to spread blue icing first. Then, swirl in some white icing. Then, paint over the whole thing with a thin layer of blue piping gel.

I used royal icing on the waterfall cake in my avatar. Let the blue royal harden a bit then pipe white over.

I just did my first waterfall. I used buttercream icing and mixed in some blue, but didn't mix it all the way. That left enough white to give a nice effect. I just posted a picture of it today in my photos. There are lots of methods, and I think they all turn out quite nicely.
