I was wondering if any of the experts here could help me. I pm'd the owner of the cake but she has not been able to reply yet so I hope someone else will have some insight as to how the rainbow was made on this cake. Also, would you use tip 12 for the clouds?

Any suggestions/advice would be most appreciated!

The rainbow is made using a template with royal icing...

Here is a template...

Here is the cake I made with it....

It almost looks like each color is a ruffle (with the rose tip).

It looks to me like the rainbow on the original cake is made with pipe cleaners.

Pipe Cleaners!?!?!
Hmmmmm

Do I attempt RI or do I go to Michaels to buy pipe cleaners?

I made mine with RI and it was very easy!!! and it's edible

you can also roll strips of colored fondant...bend...and let dry!

sorry, but i don,t believe the original cake used pipecleaners. i think there was a pattern used.. and then royal icing. stars or zigzag piping?jmo

In case anyone was wondering, I went with the fondant suggestion and it turned out much better than I thought! I used tylose glue to hold it all together.
Thanks for all of your input.

Skirt you cake came out great!

Just wanted to add that I think the 1st cake pics rainbow does look like it's made out of pipe cleaners.

i would use royal icing with the star tip on wax paper it won't come off i use parchment with flowers i want to take off, i'd put it on cardboard on both side's . There is a picture of a rainbow in the class one cake decorating course something thin but corrigated so you can put in squewers between the cardboard to hold it up

Thanks for the kind words xstitcher

ninatat, had I done it that way, the birthday girl would not have been able to eat the rainbow the way she did yesterday!

I think the RI rainbows are all lovely. I would go with that.

Just my two cents on the original pic question. It looks like she strung peices from a candy neckless in wire. I see lots of little rings. Or did somekind of embroidery stacking technic with RI. -like those wonderful embroidered flowers that look like real embroidery.
