This pattern will not center equally on both lower and upper stairs. .......what to do, ....what to do. Pattern is a Millikan geometric called Linkage Blackstone. My sketch does not resemble the Millikan carpet...... just a diagram for illustration purposes. There is a single large bedroom at the top of the stair case. Most of the time, and by most house guests, the carpet will only be seen from the downstairs viewpoint which would of include the riser on the landing. Should I center the pattern on the lower stairs and landing riser and just let the upper stairs fall wherever they fall? ........or center the upstairs section too, and let it misalign with the landing?
