I do this too! Line the fabric up where it wants...as close as I can to lining it up. Also, make sure you're not cutting too fast, and that there are no tucks of fabric hidden in the folds. Sometimes when I have too many layers this happens. Make sure everything is nice and flat, the ruler is lined up correctly, then slowly cut.
