Fire patterns

Hello,
Alongside with spinning, I would like to experiment designing fire patterns on the pavement - be it a street pavement, a lawn - exploring different forms: circles, etc. What kind of fuel do I use?
Where can I find tutorials?

I have done something similar to that where i lit my cane from a trail of fuel about 9 feet away. what i did was put a nail through the top of a water bottle and fill the bottle with my fuel and lightly squeezing it will give some good control.
