A brown seamless wood texture in a form of stripe pattern. The result has turned out pretty well, in my opinion.

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!

Wild Oliva or Oliva Wilde? Darker than the others, sort of a medium dark pattern.
