This set contains 10 brushes that are 2500 pixels in size and contain various curvy rings. These remind me of Saturn’s rings and could be used for some neat space backgrounds or something like that. This brush set was created in Adobe Photoshop 7 so it will work in PS7 or any version newer then that. It will also work in Gimp. If you want to generate a .png of each brush, you can use abrMate to create them for software such as Paint Shop Pro. Have fun with these free brushes!
