Now let’s look at drawing the brim. For the front part of the brim of the cowboy hat, we can draw what from this angle will look like a rhombus shape.

Begin by sketching a line going down at an angle from the front lower base of the crown.

Then, from the bottom of this line, sketch another line going to the right. This line should be roughly parallel to the base of the crown.

Finally, sketch a third line going from the last line to approximately the center of the crown base. This line should be parallel to the first one you drew. You should end up with what looks like a diamond or rhombus shape.
