I use a permanent Sharpie to mark the cutting line all around the quilt. This becomes a "virtual" cutting line in that I act as if the quilt were already cut along that line. If I need to mark on the front of the quilt instead of the back, I machine baste on that marked line so that I have a "virtual" cut line on the back too. The machine basting stitch goes really fast because I just feed the marked line into the presser foot.
