f*** with filters.
but heres my advice for that one.
Starts a 10 x 10 doc.
2 pix inside of the border of the doc, trade 1 pix border around the entire square (keep it 2 pix away from touching hte outside of the square at all times)
then what you do: define the pattern.
go back to your original doc, fill it and massacre the opacity.
You also have to learn how to f***in cut dude, you cannot just use the wand
