Based on 1k grayscale psd files with custom icons these brushes are ready to use as they are. Just extract them to your brushes folder and navigate there with lightbox in zbrush. Or just double click on the file in while zBrush is open. Make sure you have enough resolution on your mesh and there you go! See the example image in the cover! These work excellently on any cloth types but especially with leather and denim materials. I included the psd files also, but they are tweaked for zbrush so other programs may or may not need tweaking of their own.
