If you’re adding multiple borders, first join border strips for each side into a single border unit. Fold each border strip in half crosswise; press lightly to mark centers. Fold quilt center in half in each direction and press lightly to mark center of each edge. Pin a border strip to quilt center edge, matching the center marks and allowing excess border strip to extend beyond the corner edges. Sew together, beginning and ending the seam 1/4" from the quilt center’s corners. Repeat to sew border strips to remaining edges. Press all seams toward border.
