I just remembered another tip for you. If you are cutting sizzlits and the top plate is really cut up you can place a piece of scrap bond paper on top of your cardstock. That way the bond paper will absorb some of the cuts from the cutting plate and they won't go into your cardstock. i found this very helpful when cutting delicate sizzlits like the SU Little Leaves sizzlit.
