I haven't been knitting very long, but I've already developed a dislike for those little plastic ring stitch markers. They tend to get in the way, and they leave a trail of wide stitches down my project. Here's my solution: I tied a piece of cotton yarn around a large knitting needle, tied a tight knot, trimmed it close, and voilà - a flexible cloth marker! I don't know if others have tried this, because I haven't seen it anywhere. These don't cause me the same trouble as the plastic variety.
