First, Start out by tracing your hand lightly

It should look something like this.

Then, Start drawing horizontal lines, arching the line when you get to your hand. This line will bow slightly, like seen here.

It should end up looking like this
![](https://static.wixstatic.com/media/0f9cf1_518467eae8c04f17b8f7f6949741763c.jpg/v1/fill/w_600,h_399,al_c,q_80,usm_0.66_1.00_0.01,enc_avif,quality_auto/0f9cf1_518467eae8c04f17b8f7f6949741763c.jpg)
With the same marker you drew the horizontal lines, fill in every Four line with the marker.

This step: You will continue filling in the lines with one other color.
The next set of lines you will color half the line and color the other half with a color that will extend pass another line to the half of the next set.

Fill in what is left
