6. Next, we'll need to add some random vertical lines to give it a "wood-grain" like appearance. The first step is to simply create a new bristle by drawing a vertical line. You can use either the Freehand tool, or the Line Segment tool. Once you set your starting point using the Line Segment tool, double-click at the ending point to complete the action and exit the line segment drawing mode.

7. All the attribute settings will be the same as with the previous bristles except for the following changes:

  • Color tab
    • - Base Color: H: 27, S: 77, B: 40
    • - Base checkbox enabled
    • - Line checkbox enabled
    • - Fill checkbox disabled
    • - Gradient checkbox disabled
    • - Antialiased Edges checkbox disabled
  • Alpha tab
    • - Enabled
    • - Minimum: 9
    • - Maximum: 9
    • - Density: 100
    • - Threshold: 1
    • - Feather Edges: 0
  • HSB tab
    • - Enabled
    • - Hue Variance: 8
    • - Saturation Variance: 13
    • - Brightness Variance: 0

8. Duplicate this bristle, and change the Base Color to H: 60, S: 100, B: 0.

9. Duplicate this bristle, and then resize it so that its height is 35. Set the attributes under the Random tab as follows:

  • - Enabled
  • - Quantity: 2
  • - Coverage Area(Width): 88
  • - Coverage Area(Height): 88

10. Activate the Layer Manager and create a new layer by right-clicking in the layer list and selecting the New Layer option. Before painting the grain, you'll need to disable the other bristles first- select them in the Bristles list, right-click, and select the Disabled option. Now, with only the grain bristles enabled, making a few passes across the canvas (depending on how fast your computer is), will produce a nice wood-grain effect:

This pretty much details the fundamentals...the number of possible variations is limitless. For example, after applying the wood grain, and then using the Sharpen filter (available by right-clicking on the Canvas, and selecting the Filter->Sharpen option), you'll get something that looks a little more aged:
