Yes, Pzazz, you will have a fight on your hands with trying to machine quilt a bed quilt on a regular machine! Hand quilting the center would be the only way possible. But there might be another option.....I had a thought, and it was 'validated' by my noticing a store bought quilt- the backing had 3 seams horizontal. Which backed my hunch...what if we divide the bed quilt into 3rds? Then pieced each 3rd together, matching seams, etc.? We would be able to machine quilt each section, then join them together. By joining them together, the fabric bulk would be to our left. It's an idea worth pursuing.
Any thoughts on that one?
Kind Regards,
