In this tutorial, we’ll look at a very basic way to creating a wood texture with knots.
1. Open a new document in Photoshop. Set the dimensions to 200×200 px.
2. Create a new layer, name it “Wood Texture”.
3. Use the Paint Bucket tool and fill in the layer with the color that you want for your wood.
4. Goto Filter > Render > Fiber.
5. When pop-up appears. Set Variance to 16.0 and set Strength to 13.0. Click OK to accept the changes.
6. Goto Filter > Liquify.
7. Use an appropriate size brush to push the grain texture out in order to distinquish where the knots in the wood will go.
8. You should now have a wood texture with some knot shapes applied.
9. Finally, goto Image > Adjustments > Brightness/Contrast and adjust the sliders to get the depth of the grain that you desire.
