How to create custom static brush in the gimp

I'll show you how to create custom static brush for use with the GIMP.

1. Create new canvas, mine use 375x50 px. If you want a brush that have own color, use RGB mode and fill the canvas with transparency. If you want a brush that have color depend from brush dialog, use grayscale mode and fill the canvas with white (not foreground or background) like image below


2. Create your image, maybe you want to create to another layer so you can edit later. Or, open example image as new layer. This image originally from deviant art, a photoshop brush. Then I convert into .png with some converter.


3. Save this image as GIMP brush (.gbr). When the dialog shows up, select flatten image and press export.
   
4. Voila! and you're done. Just copy your new brush to brush folder and click refresh brush dialog.
5. Your new brush will shown. It's time to test your new brush.

This is my resulting brush.
