Check the drape out on the cake half way down. The one with with pink roses and the blue and green drape. How was the two color drape created? http://images.google.com/imgres?imgurl=http://www.realbakingwithrose.com/doublesided_sash_cake-thumb.jpg&imgrefurl=http://www.realbakingwithrose.com/2008/03/&usg=__jy1kyDrCFtsvhdik4xF4o5sERGg=&h=480&w=480&sz=246&hl=en&start=47&um=1&tbnid=KMjajzKKGHbZuM:&tbnh=129&tbnw=129&prev=/images%3Fq%3Dheat%2Bwedding%2Bcakes%26start%3D40%26ndsp%3D20%26um%3D1%26hl%3Den%26rlz%3D1T4GGLD_enUS311US311%26sa%3DN
You just roll out two thin sheets of the colors you want, place one on top of the other, and roll that through your pasta machine. It looks really great on some flowers (I've done two-tone tulips this way) as well as bow loops. It's easy!
What a pretty little cake that is!
the colors are similar-do you think she just dusted one side with petal dust?
I think cakepro is right. Two colors pressed together. There is a technique called "Patterned Paste" too that it might be. Same thing - two colors, one on top of the other bonded with a light water wash then rolled to press together. It looks beautiful!
I learned the two-color trick from Nick Lodge. We had to make rose calyxes using green on the outside and white on the inside for the species of rose we were making. Pretty fussy for calyxes but beautiful for drapes, flowers, bow loops, etc. The only thing we did differently is not use a water wash to bond the colors together, as they stayed together once rolled through the pasta machine.
