You can vary various things to get the effect you want, here is
something that is perhaps a little coarse and dark compared to what you
want http://members.pcug.org.au/~rcook/cf1.html


I personally found nothing remarkable didn't like the examples you provided  -
I guess going to filters-noise-hurl, followed by colors-desaturate
and colors-curves to fit the gray ranges to desired values should
give you better results.

I am more for stuff likje this when talking concrete, though:

A little of the above + secret sauce + bump map

secret sauce recipe:
1.new image
2. filters-noise-hurl
3. colors-desaturate
4. layers-duplicate
5. on the bottom layer,
filters-blur-gaussian blur, radius 3
6. on the top layer, set the layer to darken only
7. combine the 2 noise layers
8. create new layer, fill with medium gray
9. filters-map-bump map; source = noise layer, angle = 10º.
10. optionally use color-curves to fit your gray range.









 Hi Owen.

 That tutorial creates a very regular and smooth looking pattern. Marks
 background image looks a lot less regular and less smooth. It looks more like
 an artifact from nature, like a sandy surface, where the tutorial pattern
 looks the opposite - the product of a mechanized process.

 Thanks for chipping in, but I'm after an effect that is quiet different.

 Hi all.
 
 I'd like to be able to create a rough, even texture.
 The perfect examples are these:
 http://data.markjardine.com/tumblr/img/bg_texture.png
 http://data.markjardine.com/tumblr/img/button_nav_right.png
 
 The texture dominates the design style at:
 http://markjardine.com/
 
 I know that style is a little trendy and all. But I still think it's
 a nice effect. I've been able to achieve it before, but I can't
 figure out how to do it again.
 
 I can't quite get it with just HSV noise.
 
 I've been playing with the noise generator: 
 http://registry.gimp.org/node/13016
 
 I can get kind of close with just gaussian noise, stdev set to 2.5.
 But my result seems a little blurry.
 
 How would you guys create this effect ?
