If you are just doing crosshatching or simple lines you can mark the quilt as you go after it is sandwhiched by using masking or painter's tape. It comes in various widths. You simply quilt on either side of the tape and move it. Line it up with the last line of stitching and quilt on the other side of the tape that has no stitching yet.
