Well you sound like me! I have an OTT-light wannabee I got at Big Lots and I aim it at the presser foot. It does give me good light. As far as trying to stitch in the ditch, you could stitch near the ditch and use the edge of the presser foot as a guide, or you could use a "wobble stitch" where you intentionally have it jiggly, or, you could use a decorative stitch in or near the ditch. You will get lots of good suggestions from the wonderful quilters on this board. Good luck and post a picture when you are done!!
