Drawing a Nimbus a Pans

While this design is rather rare, it's very easy to do.

Here are the steps to making this halo:
Draw your figure first.
Starting from the center of your figure's head, draw a line going upwards. This line should be shorter than the head is tall.
Add a new line every 60°, like the spokes of a bicycle's wheel. These ends of these six lines are the outer corners of your halo.
Place a mark on each line. The further in these marks are, the thicker the halo's border will be, so I would suggest placing them on the last third or fourth.
Connect the marks and the ends of the lines to each other to complete the outline.
Lastly, take a moment to clean up your work and finish the halo.
