Your quilt is outstanding. Such work! I too have yo-yo's for a quilt. I've been thinking about bar tacking them together on the sewing machine. It sure would go quicker. I'm thinking the bar tack might be more noticeable than I'd like so maybe a decorative thread would take care of that. I would welcome other ideas. I don't think I want to join them by hand, but then again that would be a good traveling project.
