Gimp is the only tool you need. It has two powerful filters.

First, take an image of your material. For example, this is a scan of an ISOPLY sample.

ISOPLY.JPG

Tile this image 4 times with the Gimp filter "Map -> Small tiles" ("Carte -> Petit raccords" in french) We can see seams between each repetition. It's not so beautiful.

Thus, you would rather blur the image sides to make it tileable without seams. Use the Gimp filter "Map -> Tiler" ("Carte -> Rendre raccordable" in french)

And then tile it again to look if the result is good.

As you can see, we don't see seams anymore. But there is still a dark piece which bump into our eyes. You should take care your image has not a too constrasted area to avoid this effect.

You could also use the resynthesyser plugin for Gimp. It makes pretty good results as you can see but it's a quite slow software.
