Step 2 of 6
The line on the bottom
What you should end up with
The white edges with green and blue sit at the bottom front and bottom back. Together with edge orientation this step is called EOLine.
The diagram shows the cube from below, where the white face is.
How to do it
- No quarter turns of F or B here and no rotating the cube: the edges would go bad again. F2 and B2 are fine.
- Put the green edge at the bottom front and the blue one at the bottom back. They may be turned together: at the end a D move lines them up with the centres.
