Browsing the web, I found http://fimocrazy.blogspot.com/2006/01/tropical-flawer-totorial.html and I thought that if this could be done with polymer clay, why not with icing.

 

It was getting on for the evening, and I didn't have any sugarpaste hanging around, just marzipan but I was desparate to give it a go.

 

First I used the method from the link above to create some petal canes (although mine aren't as beautifully blended as the clay ones - polymer clay modellers use a pasta machine to produce those lovely blends and I don't have one of those at the moment)

Balls of Marzipan ready to start

First I guessed at how much I would need of each colour

Coloured Marzipan

All coloured up (note the cocktail sticks in the corner - I dip them in the colouring then wipe the colour onto the marzipan so as to make sure I don't add too much colour)

 

Two colour roll of marzipan

I rolled a sausage out of the pink, then rolled the blue into a sheet and wrapped it around.

Tube cut in two

Now, following the instructions at the top I cut the tube in half down the middle

Squish one side of the half cane

Squish one side down, then roll it up, starting from the flat side, keeping the pink inside:

Rolled Cane

It's hard to see, and hard to describe, but I'll try again - you turn the squished cane over, so it's pink side up, then starting from the long, thin side fold/roll it towards the other side so that you end up with the pink in the middle, the blue all around the outside again, but with a little blue swirl where the squished side was.

Now I roll out the cane to make it thinner/longer and using a sharp knife cut little sections off to build my flower. I didn't put my marzipan in the fridge to firm up, but if I had, it would have been much easier to work with I think.

Building the flower from petals

I've rolled out the cane a little more to make the smaller petals on the outer ring.

 

Next I want some leaves. The link above didn't have a tutorial for those, so I guessed (I've since found leaf tutorials, so I can make better ones next time)

I made them by putting light green and dark green sheets on top of each other, then pleating up:

Then I cut it in two down the middle, and placing them next to each other:

Half-made leaf

Rolled this out until they were about the right size for the leaf I wanted, sliced them, and added them to my flower

FLower with leaves

Now I pad it out with the white marzipan - so that when I roll the cane out it maintains the shape of the flower:

Padded flower

Now it's time to turn this patty in to a cane (real cane builders use much more clay so they have a thicker start) I do this by carefully and gently cupping my hands around the edges patting, then moving the disk round so I can pat from a different direction.

When it's tall enough to roll, I put it on the side and roll it until it's about an inch across:

thick flower cane

Here, I've taken my flower slices, placed them on the board, then squished, and rolled with a pin until I have a nice sheet made from the tiles (you could do this on a backing sheet of marzipan if you wanted to avoid deforming the flowers)

Sheet of flowers

This I can pick up and use to cover something as I would with a normal sheet of marzipan. I didn't make very much so all this can cover is a cupcake:

Cake covered with cut cane sheet

Here's a zoom in on one of the flowers.

Not bad for a first try!

 

I think that for my next go I'll try to get a pasta machine and use sugar paste so I can use some more of the clay modellers techniques. Also, putting the canes and models in the fridge to firm up.
