Help - A double How-To GIMP Question

[The Cartographist]

I thought that there was a thread about it already, but I can't seem to find it.

Can someone provide quick advice or a tutorial on generating a nice parchment in the GIMP? (There are tons of parchment tutorials for PS, but I'm currently unable to find anything for the GIMP.)

Along the same lines (and I'd assume it's very close), can someone provide advice or a tutorial on generating marble (the stone) in the GIMP?

Thanks, in advance. I really miss this place...

Sagenlicht posted this script for making torn old paper:

based on a tut by RobA

That might answer the parchment needs, at least.

Here is the process I use, based on some photoshop tutorial from long ago that I have since lost the location of
1) Filter->Render->Clouds->Solid Noise
2) Filter->Render->Clouds->Difference Clouds
3) Repeat 3-10 times
4) Color->Auto->Equalize
5) Color->Levels and rag the gamma to 4 or so

This is black veins on white.

Invert to get white on black.

Colorize to get a colored marble.

Make seamless if desired

Also, a nice effect is to throw another layer of rendered clouds in screen mode on top:

Oh-

And here is a coloured marble tut at the GUG: http://gug.sunsite.dk/tutorials/alastair1/
