Here I have tried to create something that would look like maple wood. Not sure how well it's turned out, but at least it looks like wood.

Same as Silver Scales, but in black. Turn your site into a dragon with this great scale pattern.

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.

Here's a brown background pattern with subtle stripes. I hope you'll like the color. If not, feel free to change it using an image editor, if you know how of course. Personally, I'm using GIMP to create these backgrounds.

This was formed by distorting an image of a background on Pixabay.

I’m not going to use the word Retina for all the new patterns, but it just felt right for this one. Huge wood pattern for ya’ll.

Just like the black maze, only in light gray. Duh.

No, not the band but the pattern. Simple squares in gray tones, of course.

That’s what it is, a dark dot. Or sort of carbon looking.

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.
