bump! also i thought i would share the process of making a new texture from scratch in a brief guide.
i started with a blank square filled with the colour i wanted to use, and shaded it very roughly

i next smudged out the borders or they would have remained visible throughout the later stages. would have been easier to just use a gaussian blur in retrospect.

started to progressively fill in the detail, starting with broad brush strokes and ending in lines 1px across. i also made the image seamless at this point, and then airbrushed in some shadows & highlights

...

next i used another wood texture as a colour overlay - makes it look less monochromatic and more consistent with other textures in the scene
to make the image stand out even more i used the GIMP to mimic a bump map effect

enough work for one day! but still not finished!
