So how did you make them?
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.
