Try using painters blue masking tape to stick to your quilt top for quick marking of the straight lines you desire ie from corner to corner and then the continuing lines on each side of your first stitched line, one strip at a time. I've used this trick I saw somewhere and it works really nice for straight line quilting in a grid or diagonals. It comes in various widths too for whatever width desired. Just put a strip on your quilt top where you want, quilt the stitch line and then move the tape to the next line you want. The tape keeps it's stickiness for a bit so you don't need all new tape strips for each line. However, if you just want to stitch in the ditch, you don't have to do an overall straight line quilting unless you just want to since all the stitch in the ditch stitches will hold the quilt together nicely. Have fun.
