|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.|
See a sample of a faded background here.
