Matting Board Cut to Size
Start by putting the mat board face down. I’m going to mat a watercolor for a standard frame. This is for a 16 in x 20 in frame. I want the window to be smaller than the paper so the board holds it down. Always double check the measurements before cutting. After I draw the cutting line, I put the watercolor on top to make sure the measurements are correct.

Looking at the corner, assures me that the window is the right size.
Slip Proof Ruler and Bevel Mat Board Cutter
When using the bevel 45º mat board cutter, place the cutter as in the picture above or the bevel will be the opposite of the desired result. The blade has to be changed often or it will become difficult to cut and start ripping the board. When cutting the corner, cut a little bit past the corner so the corner has a clean cut.

Here is a video of some of the small watercolors that I matted first. If you are out of practice like me or doing this for the first time, it’s a good idea to start matting small watercolors until you get the hang of it.
