Measuring and Marking
Measure the length of the near the top of the walls where the moulding will be installed. Write down the measurements. Double check the measurements.
To transfer the measurements to the moulding, lay the moulding wall side down on a ruler with the decorative edge facing forward.
Notice that I didnít make the mark directly on the end of the moulding. I never do. It can be difficult to catch that end dead on. It is much easier for me to move it over a smidge to get a good, clean cut. Also, it cutting an outside corner cut about a 1/2" or more from the end of the strip. I also draw the direction of the cut.
