So I need to build a layer with offset bricks, which I have managed to figure out. However, the corner is a problem. The dark bricks in my pic need to be in that position. How do I fill the gap between them around the corner?nI'm assuming i will need to use a headlight brick but how? 
(I have managed to work out what to do in straight line, but now the corner is a problem.
