1. Clean the bulb and degrease it.
2. Pre-draw the lines with a marker you can wash off.
3. Put the bulb in a bowl of sugar (it will stand and you can paint from each direction easily). Then start with the contour.
(missing 4 on purpose because it just tells you to draw the lines :))
5. If you wish you can fill the spaces with a brush and some paint.
6. Pull some twine/yarn/wire through that flower-like thing.
7. Glue the flower-like thing to the top of the bulb with a glue gun.
