You could swag it over, but when you hang the chandelier you'll need to make sure the ceiling area can handle the weight. More than likely, bracing will need to be put in. If the location can be moved, without the need of a junction box, I'd vote for that. Unless you have a popcorn ceiling, most textures can be matched. Paint matching would be another story,.

We have the same problem in our dining room. And the real 'ACK' part is that we gutted our whole kitchen/dining area and removed the old ceiling, so we could have addressed it properly the first time. Once the new dining room table was in, it was obvious we would be moving it off centre (pathway to deck is behind table), and we're kicking ourselves. DH is planning to buy a plaster medallion to put up on the ceiling, so that the edge of it will cover the old hole. Luckily, he is an electrical engineer, so he can do the rewiring. I COULD patch the hole, but what a LITERAL pain in the neck. So not only will the fixture be off-centre, but medallion will be too. I am pretty sure it will cost you more than $35 extra on top of the first $35 to rewire in a new location- assuming there is enough wire up there to allow the move. Ours is accessible from the attic.

How far off is it? Consider a rectangular chandelier with a rectangular plate. Track lighting - always reminds me of something from the 1980s

Thanks for all the suggestions! I have the table moved out now, it's not terrible. I'm just going to live with it a few days, maybe I'll try rotating the table for another few days and see how I like it.
