The yellow cross
Dot, L, line, cross.
Time for the last layer. First, a yellow cross on top. Look only at the yellow edges, and ignore the corners. You'll see one of three shapes. A dot, an L, or a line. If you see a dot, do F, R, U, R prime, U prime, F prime. Now you have an L. Hold the L so it points to the back and the left, like this, and do it again. Now it's a line. Hold the line flat, from left to right, and one more time. A yellow cross.
Here's a line, already flat from left to right. Make the cross.
Line to cross.
Now an L. It's already pointing back and left. Take it all the way to the cross.
L, line, cross. You've got it.
And finally, a dot. Go from dot to cross on your own.
Dot to cross. That's the whole step.
