Just to expand on my previous post, here are some rather poor drawings.
This shows how applying ribbed murrini and fish/shape murrini differ. For the former you want it to melt into a cone shape so that you can see design on the sides after it melts in.
The process for applying the two different types of murrini are different since in one smearing is good, while for the other smearing is bad.
And here is how I suggest doing it.
Just keep repeating the last two steps until it is flush.
When you start it can be a pretty long and slow process but eventually you will get a feel for how fast you can go without smearing the murrini.
