Quilt top and backing should be squared and pressed.  Backing and batting should be at least 4" larger on all sides than the quilt top.     Do not baste or pin quilt.     If the quilt has a "top", mark it with a safety pin.  Some quilting patterns have a one-way design.     Quilt must lie flat and smooth in order to be quilted flat, without puckers.  Please make sure borders do not add extra fullness.  I would be happy to provide you with instructions for applying borders.     Please remove any hanging threads and markings from your quilt.    Please remove selvedge edge from seams of pieced backing, but leave them at the side edges, if you like.
