The most important step when you are attaching borders is to measure acoss the quilt in the centre and down the quilt in the centre and take these two measurements as the lengths you will cut the side and end borders to. Do not just add lengths of material to the sides and then Cut them off or your quilt will not be square. Pin the borders onto the sides of your quilt and eas in any fullness that you may have on any side. All thebest with your project.
