Background for webpages showing as small lines, etc. How-to?

[ocalagal]

Many of the website are now using a background which looks like 1 pixel small lines.
I have tried to replicate this in many ways, but can't seem to get it right.
I have made the image in a larger version and then reduced it down to 1x1 picels, but that only blends everything together.
Does anyone know the trick for this.
I have attached a sample of what I'm talking about.
Please help!
Thanks. /emoticons/frusty.gif

1x1? man that's too small. all that'll do is show a solid background the color of the line. try creating a block that's 5x5. keep in mind that the backgrounds tile, so make sure the lines line up. that should work.
