How do I lay 2 different fondant color on a cake and it look clean like in this picture. http://cakecentral.com/gallery/1551511/1656047
I need to make clean seams like this. Please help!

Lay each color slightly overlapping each other, dusted with cornstarch, and make the cut. That way the cut edges will be identical and fit together nicely. I hope this makes sense.

When I did the two colors like this I laid the first color on and cut the line for it. Then I laid the second color on, and used the previous line (and a ruler since I was doing straight lines) to cut the second. Using my finger I rubbed over the seems to match them up.

Thank you for the help. I will try both of them and I'll see which one works for me. Or I'll be you for more help!
