Learn how to design a wood texture to fit around your artwork in this tutorial, using the Liquify and Fibers filters in Photoshop
Start with a blank document, choosing the correct resolution and document in the New menu to match your photo. Go to Edit>Fill and choose Color from Contents. Set its colour as a brown (#ac7233), and hit OK to apply.
Create a new layer and fill it with white. Now head to the Filter menu and down to Render>Fibers. A menu will open up containing a couple of sliders. The Fibers filter imitates wood well, and you can increase the strength and number of vertical lines using the adjustments. We set this one to Variance 16 and Strength 4.
At the moment the Fibers filter is black and white. Change the layer’s blend mode to Screen. To add colour, double-click on the layer to open the Layer Styles menu. Add the Color Overlay option and set its colour to a light orange (#ffc15f), mode to Multiple and lower Opacity to 80%.
Now go to Filter>Liquify, as this will allow to reshape the lines in the texture to look more like wood. Select the Twirl Clockwise tool and set its Brush Size to 160, Density to 80, Pressure to 30, Rate to 40 and Turbulent Jitter to 50. Run the tool vertically down the texture to create twisting lines.
For small knots for more realism, lower the tool’s Brush Size (using [+]) to twirl smaller parts into each other. Also, use the Turbulence tool to create more wavy lines, bending the wood texture into shape.
When you’re happy with the effects of the Liquify tool, hit OK and add a new layer, setting its blend mode to Multiply. Select the Brush tool with a dark brown colour and a soft round tip, and dap on small spots for the knotted lines created from the Liquify filter.
