how to make this pattern

Anyone know how to duplicate this? It's the texture used as a background. http://www.typophile.com:D

Hmmm, I would use a pattern to do that...

Make a pic 36x36 pixels with a certain something in it. Then edit/define pattern for future use ;). Save this li'l pic as "mybackground.gif" or something, then in your web editor choose this pic as background...

But that specific background pattern, I do not know...Can't find it in PS default patterns, so I guess you'll have to make your own...
