How big a throat does your machine have? How big is this quilt? If throat is less than 11”, I recommend using a walking foot and do straight line quilting from the center out. If 11” throat or more, FMQ and roll up the excess quilt under the throat to manage the bulk (again, starting in middle and working out, so you don’t get puckers.
