It would be a lot easier to handle this way and no y-seams -

I played around with the Y seams last night and was thinking that the way you show it here might be my best way. It's not so bad because I won't be cutting up the diamonds which Is what I didn't want to do. So with all this said, I really think joining it at that point for the long straight sides will not be a problem.
Again thanks.
