How to Doodle a Lightbulb
Begin by doodling a couple of squiggly arc-shaped lines. Make the lines a mirror reflection of each other.
Now combine both squiggly lines at the top and bottom to close off the shape.
To doodle the top of the light-bulb use three arc-shaped lines as shown in the example above. Try and keep the lines smooth and consistent.
Now add some more details to your light-bulb using several more arc-shaped lines that are part of your visual alphabet.
Add the final touches to your light-bulb by adding several more straight lines to the outer edges of the light-bulb. This will make it seem as though the light is on and shining. 🙂 And finally, add some color to give your light-bulb some character.
