A seamlessly repeating background pattern of wood. The image is procedurally generated, and, I think, it's turned out quite well.

Sharp pixel pattern looking like some sort of fabric.

Super subtle indeed, a medium gray pattern with tiny dots in a grid.

Same as the black version, but now in shades of gray. Very subtle and fine grained.

Wasn't satisfied with the original's colouring. Too much component transfer and colormatrixes yet the results are lacking a bit. So this time it is a simple black to transparent fade, making it possible remixing easily once there will be other blending modes supported as well. Probably in inkscape 0.92.

This texture looks like old leather. It should look great as a background on web pages.

This light blue background pattern is quite pleasing to the eye, it consists of a tiny rough grid pattern, which is seamless by design. That's it, if you like the color, you can use this seamless pattern in a web design without making any further modifications to it.
