What are textures and how do I use them?
Textures are just 'backgrounds' or collages of many images. patterns and gradients all swacked together and effected, and they are used on graphics to create depth and effects.

Using Textures
No matter what program you are using, just copy and paste the texture on top of your graphic and change the 'Blend Setting', to something like overlay or screen, or change the opacity.
YOU DO NOT NEED TO DOWNLOAD A TEXTURE, JUST COPY AND PASTE IT.
