Textures in Photoshop

When I work with digital images to print on my alternative surfaces, I usually create textures within Photoshop before printing my surfaces.  Putting together a new project this week, I will be doing a lot of printing and am beginning to experiment with images to see what will actually make up to surfaces in the final piece.

Here I have combined 2 photographs and used them to texture each other and blend them for the composition.
