Is there is specific way I should be doing this? I want the top of my cake green, and would like the sides white.
I don't even know *how* to search for this question....lol.
Thanks!

I don't know for sure, but I would guess that you ice and smooth the sides first overlapping very slightly onto the top of the cake, then ice the top just to the edge with the green. If you use viva to smooth that out and use a top border, then my guess it you won't see the join. I think using the icing tip for an even spread of icing would help too. I've never done it though, so maybe someone with more experience can tell you

Here is a bump - I wanted to do this last night but didn't know how

I have only done this once. I just iced the top white and stopped as best I could at the edges. then I iced the sides yellow. Smoothed with a Viva and piped a top border. Here's a pic. I don't know if there is a specfic technique for this. Except for where I stuck my finger in the right hand bottom side of the cake and had to repair, I think it came out okay.

Maybe I can help with this one. I made a Mother's Day cake with different colors. I'm sure there is a simpler way to do this but what I did was frost the sides of the cake first and smoothed out. I then placed a piece of paper in the shape of an oval (that I covered in contac paper) and placed in in the center of the cake. I then covered the top of the cake in pink icing all around the oval and some even on the top of it. I smoothed the icing a little and then gently removed the paper oval insert. I then took white icing and piped it with a number 5 tip and iced the inside of the oval. I then waited for the entire top to crust and smoothed with the Viva towel method. It really was simple. Your borders cover up any flaws where the colors meet. I'm going to try to insert a picture. Alrighty, hope this helps.

Thanks, that's perfect!

Margie, your cakes are so beautiful. I saved the white version of this cake from the gallery. It's even prettier with the two-toned icing.

Thanks so much Denise for the compliment. That was really kind of you. Actually, I think I liked the all white cake in my photos better also. Maybe it's because I had the problem with the dark pink specks in my pink icing. Anyway, thanks again!!!!!!!

The instructions for icing a cake upside down to get a smooth top is on this website. I was wondering if that would work well with two colors on a cake?

It should work with the different colored insert on top--especially if you plan to pipe a border of some type around the border where the color changes. I'm not sure how it would work for doing the sides in a different color from the top. Normally you would want the side color to cover the outside edge of the top icing, and then you'd pipe a border to cover any unevenness or small gaps. With the upside down technique, the top icing would cover the top edge of the side icing. It might be okay, but you might need something to cover that area if it comes out uneven.
