These brushes were all made in Adobe Photoshop CS3, and should work in any version after Photoshop 7. Each set contains at least twelve different brushes of varying sizes. As a general rule, most of these brushes are quite large, ranging all the way up to a thousand or so pixels, but they can easily be resized. You can use them for whatever you want, provided you follow the Terms and Conditions. Just click on the image to download the brushes.
