Ok guys, i made this jeans material for Cycles. In my opinion itlooks ok and works well for larger pieces due to it beeing seamless. Real jeans is basically a cotton and silk material with hard and close stitchings, so this might not look a hundred percent right for all purposes.
With this material you get textures and a bunch of nodes that can be changed to add more to the base material. You also get the XCF file(GIMP projekt file) use to create the textures. With the XCF file you can change and add lots of stuff to the original texture with very little know-how. Just stay away from the very edge if you want to keep it seamless.

That image is 2048x2048, the "details" are easy to see.

If you guys want the XCF file for the textures then go to this link: http://dl.dropbox.com/u/1070700/gimp%20 ... %20WIP.xcf The XCF is about 122 MB big.
Fun tip:
To add more realism to the material, add a few small strands of hair to the model thats covered in this material. But not too much and make sure that its small and very subtle.
