did you make the pattern or did you download it? if you downloaded it, can you tell me where i can download it? and if you made it, can you tell me how to make it? `=) haha. i'm starting to believe i'm a big bother.
open Photoshop
go File > New
Set the width:
1 pixel, height:2 pixel,  at the contents, choose 
transparentnow you will get a very very small drawing area.
next, 
zoom in 1600%
change to 
pencil tool, choose the pencil diameter as 
1 pixel and click on the white colour. colour only the top part of area.
go to 
Edit > Define Pattern > OKnow you have the line pattern!
to apply, open a picture you want to apply the line pattern.
create a new layer. at the same layer, go 
Edit > Fill > OK.
next go to the Layer Palette, choose from Normal to Soft Light.
there you have it.. the line pattern.
hopefully its ok~
