Practice, just scramble it and practice the cross. Know where the pieces go in relation to each other.
I just opened jnet and got this:
F D2 R' F B D U2 R U2 R' U2 D R' B' L2 B F U B2 L B R' L2 U' L'
(scrambled with white on top and blue on front)
Flip it over so white is bottom and green is in front.
What i see is D L F' D L to solve cross
I guess that is a decent example of knowing the pieces in relation to each other, dont necessarily place them one by one.
On another note... add 8 more moves and u solve 2 pairs... if you do D L F' D U2 L U F' U F L' U2 L
