If you ordered youe Cameo from Linda you received a separate blade for gum paste. Use the black blade for paper, and the mat that comes with the Silhouette. When you cut gum paste, use a different mat and the gum paste blade. Wipe down the machine between paper and sugar work. If you keep it clean is will be safe for both sugar and paper work. I don't cut paper very often, but when I do I never feel like it is no longer safe to cut gum paste. Remember, different mats and different blades.
