How to start cutting decorative cornice in a room to match mitres

Where you start with DECORATIVE CORNICE is IMPORTANT.

Standard bedroom layout With any patterned cornice, there will always be one mitre that does not match up. This is called a BLIND MITRE. The blind mitre should always go in the least obvious corner. In the typical bedroom layout the blind mitre goes behind the door. Corner "C" in the diagram Start by cutting length no 1. This is the most important wall to have the mitres matching, as it is the first wall seen entering the room. Measure the length of the wall and center the measurement between 2 equal points on the pattern. This will give you the same mitre, on each side. Cut each length in order listed, mirror each mitre as you go. Except when cutting length 6 mirror the mitre to, mitre "b" The unmatched mitre will be behind the door in the least obvious place.

Room layout with a feature wall If you have a room with a feature wall, this wall is the first to cut centering the miters as described above. Cut the cornice in the order in the diagram. Miter "D" becomes the blind miter tucked away out of sight.
