Grab the Creased White Paper high-res texture above, free for any use. The texture image is 10 x 6.5 inches at 300dpi, making it perfect for commercial print use.
While you’re there, check out all the other high-quality textures at WildTextures. I love the site because it appears to focus on quality rather than quantity like most similar sites. Textures are conveniently organized by subject, such as: wood, metal, leather, stone, grunge, fabric, and plenty more. Definitely a site worth bookmarking!
