Tips about how I made the OrangeIcons.com promo wallpaper (see wallpaper).
For my new website, orangeicons.com, I decided to design a promo wallpaper, in brand orange color. Here is how.
Create new document, fill the first layer with solid orange color, and apply Gradient in layer effects (blend mode = overlay). Or, simply use Gradient tool to fill the layer.
Create new layer (Ctrl-Shift-N), then, important!, open Paths tool window, and create new path. Use Pen tool (P) to create a curve similar to shown here.
Switch to Brush tool (B), choose a brush with small radius (2-3 pixels), and in Paths tool window, click Stroke button (2nd in bottom row). If the line is not wide enough, click Stroke again. Then, remove the path, we will not need it any more.
Hit Ctrl-J to duplicate this layer. Then again. And then...
..make another 50 copies of this layer! Use Move tool to move last layer to the other side of the image.
link all layers with curves (to do that, click Link icon for all layers). Be careful not to link background layer!
