Here’s a way to start with the wood grain.
Create a canvas and apply noise to it. Use a motion blur with the angle set on 0 and adjust until the noise has been stretched out to a lenght of your liking. You color this in a number of ways. I like to create a new layer with a wood color with a transfer mode of “color”.
From there you add othere filters to the texture like sharpen or Gaussain blur. Just play around with it to get the texture you like.
From there you can add a subtle gradient, use some noise to some sharper highlights. You can also create a pattern to match the boards and give them a bevel emboss, then try using a transfer mode (like overlay)for the layer.
Hope some of this helps
