Artist tip with pencil

Artist tip: As with any drawing it’s important to recognize how much space you are working with.

To do this, point to the middle of your paper with your finger or pencil. This will tell your eyes how much space you have to draw in.

It does not have to be exact! 

Let’s get started

How to draw a lightbulb base

1. Draw a slightly curved line just below the middle of the paper. This is the bottom of the bulb.

2. Next, about a finger width below that line, draw another curved line, just a little shorter.

3. Draw vertical lines connecting the 2 curve lines. Then draw a long zig zag line inside the rectangle shape that is made.

4. Make the sides of the rectangle, wavy where the zig zag lines tough the sides.

6. About 2 finger widths up from the big rectangle shape, draw a circle.

This will be the “body” of the bulb, draw it a little wider than the bottom.

The Best Part: Color/shade/fill with pictures. Your choice Artist!

Artist’s Tip: Take your time.

I used a regular pencil to shade most of the bulb, I left it blank before the edge of the bulb. I left 2 square areas where the light would be reflected.

Also, I left a lighter space in the bottom area. This is usually metal so it would be darker than the bulb. Then everything is blended gently using the clean tissue on my finger.

Blending creates the smooth texture on the bulb. Use the eraser to clean up the areas that are meant to be white.
