A repeating background of thick textured paper. Actually, it turned out to look like something between a paper and fabric.

This one is super crisp at 2X. Lined paper with some dust and scratches.

I guess this is inspired by the city of Ravenna in Italy and its stone walls.

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.
