>>"Betty Edwards" technique: notice the four corners, an imaginary "X" and the white space (negative space) on the page.

I know "blip page", but I need 'X' technique for computer reading.

I just CAN'T see (imagine) that 'X' in the page?!?!

Do you see words clearly when you try 'X' technique?

And does it mean that I need to look through computer screan when I try 'X' technique?
When I try 'X' technique I somehow get myself to look beyond (through the center) computer screan or beyond single-sheet paper? And all words are blurred. Is it OK?
