Step 2 Select a watercolor brush for the Brush Tip Shape (Window > Brush). You can download some really good ones from the Brusheezy website at

Step 3 In the Brush tab, select Shape Dynamics, change the Size Jitter to 100% and the Control to Pen Pressure if you are using a tablet – I highly recommend using one for this tutorial. Change the Minimum Diameter to 0% and the Angle Jitter to 100%. Then select Flip X Jitter and Flip Y Jitter.

Step 4 Select Transfer to finalise the Brush specifications. Next, change the Opacity Jitter to 100% and use Pen Pressure again for the Control options.
