Proper Tools

• Straight and bevel edge cutters
  
  A mat cutter is crucial for a professional-looking mat. Cutters can be purchased at hobby and craft shops. Mat cutter kits will include a straight-edge cutter and a bevel cutter, as well as the cutting guide. The straight edge is used for the initial cut of the outside of the mat. The bevel cut will give a slanted cut and is used for the inside of the mat that surrounds the photo.
  
  Use a metal rule to give straight lines to mark your cuts. Wooden rules have a tendency to bow, and the guidelines will be confusing to follow. The first measurements and cuts will be for the outside dimensions of the mat. These cuts and measurements are critical to the look of the finished project. All other measurements will be made based on these cuts.
  
  Guidelines are always marked on the wrong side of the mat. Mark the corners clearly and do not cut past the guidelines. All cut marks will show on the right side of the mat and will appear unprofessional.
  
  Replace cutting blades as needed to ensure clean cuts. Dull blades will cause a frayed border and will detract from the photo. If you notice places on the mat that are frayed, do not pull off the jagged edge. Use straight-edge nail clippers or scissors to cut the uneven edge. There may be times that a corner has not been cut completely. In this case, do not tug to loosen the mat. Use a sharp blade and carefully finish the cut.
  
  

Mat Size

• Deciding the correct size for a mat border will depend on the size of the picture or the picture frame size and personal taste. An 8- by 10-inch frame will accommodate a 1½-inch or 2-inch mat. A 4- by 6-inch photo will look at home in these dimensions.
  
  When cutting the window for the photo, leave at least ¼ inch of mat to cover the edges of the picture. Narrow borders that are less than 1 inch should be used in small frames.
  
  A nontraditional look would be a frame size of 18 by 22 inches, with a mat border of 4 by 6 inches. This only allows for about a 6-inch window, but it is a beautiful way to showcase a single image photo, such as a flower. Trust your instincts, and don't be afraid to be adventurous when deciding on the mat size. In addition to showcasing your photos, you are also adding your own creative touch.
  
  

Double Matting

• Adding a second or even a third mat will enhance any photo. Extra mats are cut in the same manner as a single mat. The important thing to remember when marking the measurements is whether the mat will be on the top or the bottom. The bottom mat will have the widest edge and show the least amount of color. The top mat has the narrowest border, but shows the most color. The difference between the inside edge of the mats is normally ¼ inch, but this can vary, depending on your preference.
