@cathyjc sounds right. That way the bulk of the quilt will be to the left and only the collar will be to the right. Although I think I would have tried to sew the inner collar to the inner fabric and the outer collar to the outer fabric (with the orientation as Cathy describes) then put the insulation in the collar and then put the insulation in the main part of the quilt and tacked the collar insulation to the body insulation before sewing up the main quilt. In order to avoid a sewn through seam at the lower edge of the collar. For cold spot reasons. But would be more complicated to do it like that. Where does the drawstring go? At bottom or top edge of the collar?
