Mitering Inside Corners. 1  1. Measure the angle of the corner. 2  2. Set a compound miter saw with the correct angles. 3  3. Cut the right inside corner.  4. Set the miter saw angle 1  again. 5. Cut the left inside corner.  6. Fit the two pieces together before nailing them in place.
Next lay the piece with the cut against the wall in the corner and make a mark exactly where the outside corner is. As you can see in the diagram the cut is 45 degrees as in the corner. After the first piece of quarter round is cut for the outside corner we then cut the next piece. This time make the 45 degree cut in the opposite direction as the first one. Notice how I leave this piece long to extend past where the wall ends. I do this so I can make sure the outside corner joint fits tight together.
