When it comes to some patterns, illustrators, in general, face the tough task of drawing repetitively. They draw flowers, vegetation, stars, leaves, hair, raindrops and even manufactured things like bricks. In this class, we will just focus on ground vegetation. We'll see how to increase the productivity and the uniformity of the patterns using the Photoshop tool 'Brushes'. The students will have the opportunity to create their own shapes of the brushes they'll use, designing them directly on a Wacom tablet or, if they don't have it, on a sketchbook and scanning them. In order to be more confident, I recommend you to watch my class Drawing Leaves Quickly in Photoshop before watching this class. But, feel free to start wherever you want.
