Here’s a quick Photoshop tip for creating Brushes from Shapes
There are plenty of Shapes that come with Photoshop, but did you know that each one can be converted into a Brush?
Apply a Shape to a new layer and then go to Edit>Define Brush Preset. Give it a name and then select the Brush tool.
You’ll see your new Brush at the bottom of the thumbnails. Apply scattering and spacing and more from the Brush palette.
