Abstract: The process for crafting paper includes providing a double-sided mat having a cutting surface on one side and a scoring surface on an opposite side. Both the cutting surface and the scoring surface each have measurement indicia thereon. Paper is scored or cut on respective sides of the mat with a ruler having a channel formed therein. The channel is capable of receiving a scoring knob or a cutting blade for precisely cutting or scoring arches, circles or straight lines. The mat and ruler are also configured to construct box tops that precisely fit relatively smaller box bottoms.
