The way my house is oriented is the main living room opens to the dining room area, similar sized rooms that share the same main wall, but have a large 5' opening between the 2. Looking at my lame description below of how it looks I plan to start laying the floor against the wall on the top left side, going up and down and across to the right, BUT once I get to the opening of the two rooms how do I fill in the other side behind the separating wall without messing it up? I hope this makes sense.
Can I just start doing the living room and then come through the opening and once I have a long enough section I just go back or back fill to the left?
