Normally I'm opposed to photosourcing (because back when I tried it I had a crappy digital camera), but as of late I think it's a practical means of getting textures.
Took it into Photoshop, selected the paintbrush, and began fixing the edges. Then I set it as my secondary monitor's wallpaper so I could see how it tiled and then attempted to remove all noticeably repeating features.
As for the trim-ish things on two of the textures, the middle sort of embossing bit is a texture from my old bridge model and the rest of it is hand-painted.
If anything, i would adjust the contrast curves (they seem quite light over here, you know, kind of wo. a dark side on them), specially the ones in the lower line.
