How did you measure to determine the length of each BORDER strip? Three places on the top:...top, bottom and center....cutting each BORDER the average of those three numbers, if there was a discrepancy.......dealing with three borders sewing each one individually is tricky......too bad you can't sew the border strips together, then sew to top mitering the corners..... Got to get those waves out now..will just look worse if quilted with all that fullness....
