First thing we need to do is open the image you want to apply this affect to.
This tutorial is great, as it combines alot of different Fill Pattern's together.
Phase One:
Press X then and then D on your Keyboard.
S1: You need to make a new image sized 6 pixels x 6 pixels with a tranparent backgound color. Zoom in all the way to 1600 and select the pencil tool.
With your pencil tool at size one pixel make this X:
Now go Edit>Define pattern.., name it "X" and press okay.
S2: Do the same as the last step but this time, make a line, like this:
Name it "line".
S3: Repeat step one once again, but draw a square, and name it "box".
S4: Do step one, once more, but this time draw a line round the edge, and name it "grid."
Phase Two:
Get your original image out (The one you want to apply this to). You
have defined all of the smaller images we made earlier, so, they will
be here: Edit> Fill> Custom Pattern.
Now go Edit>Fill> and choose the "line" one, set the opacity to
30%, press okay. Now do the same with "X", then with "Box", and last
but not least "Grid."
You should now have something like mine:
If not, don't worry, just keep on trying.
