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.

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 background pattern contains a texture of yellow wood planks. I think it looks quite original.

The first pattern on here using opacity. Try it on a site with a colored background, or even using mixed colors.

Could remind you a bit of those squares in Super Mario Bros, yeh?

This seamless background image should look nice on websites. It has a dark blue gray texture with vertical stripes, it tiles seamlessly and, like all of the background images here, it's free. So, if you like it, take it!
