Hi!

I made a thing where you can browse for TPT brushes (did you know, TPT supports custom brushes?) and even contribute your own. It also includes a setup guide, and a short tutorial to make your own brushes with GIMP or Photoshop.
You can see the gallery at:

If you want your brushes to be on this gallery page, please send me the following data:

• Brush Name
• Brush Description
• GIF images and brushfiles of all available sizes

Check it out!
