Alternative colour scheme. Not a pattern for fabrics, but one produced from a jpg of a stack of fabric items that was posted on Pixabay. The tile that this is based on can be had by selecting the rectangle in Inkscape and using shift+alt+i.

This is a grid, only it’s noisy. You know. Reminds you of those printed grids you draw on.

Light square grid pattern, great for a “DIY projects” sort of website, maybe?

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.

A grid of squares with green colours. Since the colours are randomly distributed it is automatically seamless.

A bit of scratched up grayness. Always good.
