Hope you can follow this.
(If you don't want to give it to a LA and frankly not all will do ruler work.) After you have 'basted' WELL, pins or stitching, plan on starting near the center. Work in a continuous path outward only partially completing a section or block, turning no more that 90+ degrees off your starting position in either direction. When you get to the edge, go back to the centre starting point and again work out in the opposite direction. Continue this pattern on either side of the stitched area carefully linking with the already stitched edge. Yes you may have to overstitch a few places/times but this way you will never have to turn your quilt 270 or 360.
