I am going to make a rainbow cake for my son's day care using fondant. i am not sure if it's going to be 2D or 3D yet, but if you can help me with both methods, that would be great.

My question is this, how do i make the rainbow stripes 'EVEN'? even tips? thought of rolling each colour into a sausage but it wont be even. I don't have a sugarcraft gun, but i do have a ribbon cutter which i don't know how to use yet. If i do use latter, i would imagine when i bend the stripes to make the rainbow, the lines would not be even. Now, a rainbow can't have any angles, can it? LOL

Any help/suggestion would be appreciated icon_smile.gif

How about making it as a royal icing runout, tracing over a rainbow template?

I would just roll and cut strips of fondant in the same size, line up and then curve together. Not sure how well it would work in real life, but that's what comes to my mind to try!

Good luck!

I made the rainbow in my rainbow/hearts wedding cake using gumpaste for a general rainbow shape template (let the template dry) then cutting each color the same size and making sure they all fit before using a bit of water to glue them down.

I know I have seen cakes with rainbows on it from the wilton course 1 cakes so someone that has recently taken the class my be able to tell you how to do it using star tips! We didn't do that cake when I took my course 1 in 2000.

thansk everyone for your ideas!!!!!!!! Much appreciated icon_smile.gif

I have never down a run out before but will read about it and see if i can do it. The gumpaste idea sounds good but i am not sure if I'll be able to lift each colour up (from table) without distorting the strips. I have seen a cake with rainbow somewhere (with instrcutions) but juts can't seem to find it. Will check the wilton site to see if there's anything.

Think i need a more or less step by step instructions on how to do this.

Does anyone else have any ideas/tips for me?

I use non-toxic coloured chalk, shave them and brush powder onto your rainbow shape. Because it's powder it blends beautifully and looks like a real rainbow. Hope that helps.
