First you make a hemisphere from fimo and dry it in the oven.
Then paint it: sclera with white paint, iris with green, blue, brown (whatever you want) and add crapped capillaries with red paint. Use acrylic paint.
Artificial flower paint if you don't like the main color. I painted mine with black acrylic paint (they were red). You can change the form of petals if you put petals on the candle (be careful). Don't put them directly in the flame, put them above it (about five inches above).
The last step: glue everything and add a hair rubber.
