How to Make a Square Monoline Brush for Procreate

Monoline brushes are so versatile! They're great for hand lettering, mark-making, or adding details to your art. 

Locate the flat brush in the painting menu. Duplicate the brush. 

Set the spacing to None. Increase the streamline to about 85%.

Change the rendering mode to intense blending.

Change the opacity of the Apple pencil to None.  This makes the brush opaque.

Make the brush smaller or larger by adjusting the maximum or minimum size.

Test your brush to make sure that you like it. 

When you're finished, make sure that you name your new brush.
