Here is a quick and easy instructable for making fire for any type of film with cotton.
Step 1: Painting It - and Finishing It
All you need for this is cotton and spray paint (red and yellow).
Do this in a well vented area and try to combine the colours in the middle to get the colour orange to make it more like fire and you don't need to be skill full to do this.
Ill add a video of me using this later cause I am still filming my video still.
