Lately, if I'm going to be quilting with cross hatching, which I do a lot, I lay the quilt top out and mark the cross hatching with a black Frixion pen for light fabric and a white chalk pencil for dark fabric. Doing this before assembling the quilt sandwich works much better. If I was going to be doing a close cross hatching, I just mark every few inches apart and then do in-between with the guide on my walking foot.
