Customize these 2560×1600px 300dpi backgrounds to your exact desires. First install the PAT file of textures, as seen in the preview at 100%, and then overlay your chosen grunge layer; swatches of 6 of these can be seen in the screenshot at 100%. In the PSD there is one layer for your chosen pattern, and 8 grunge texture layers for you to play with. Edit color overlays, opacity and blending modes to achieve a huge variety of effects from dark to light, hard to soft. Of course you can use the patterns alone, or in any other Photoshop project, and you can combine them in overlays too.
