Someone in our guild recently introduced us to using the shelf liner under the ruler and I LOVE it! I have found that the cheaper liner is best because it is thinner and doesn't produce "bulk" under the ruler, which will make it rock slightly. The one I like is white and it really does look cheap, but works the best. It really has made a difference in my cutting.
