Okay I got this tutorial from
www.designz.key-faith.com
I am changing it using my own brushes that I made.
These brushes are located

Step 1
Open a new document. I will be using a 400 x 100 one. Pick any two colors for your foreground and background colors and select the linear gradient tool. make a gradient on the canvas.

Step 6
Make a new layer and add faint brushing like before. When done go to layer styles and add an outer glow. make the blending type soft light and set its opacity to 100 percent
