Faded Backgrounds

Open your image and make a copy of it. Make any alterations to the copy that you want. I am going to make a mirror image of mine.
Copy and Paste your images (as new selections) on to a new image canvas of contrasting color so you can see where they line up. Continue pasting until you have a pattern that will repeat on your background.
Once you have your pattern you can edit it and resize it as needed. Open a new image with the same color background as your image pattern and the same size. Edit/Copy your original and paste as new layer over the new image canvas.
On the layer palette slide the opacity button to the left until you have the opacity (or faded-ness) you want for your background. Shown below are opacities of 75, 50 and 25 percent.
