the simulated fieldstone areas in the preferred arrangement the entire wall pattern is made up of a group of separate and distinctive subpatterns subpatterns 14a 14b 14c 14d and 14e being illustrated in fig1 of the drawing each pattern is rectangular and is arranged to mate side to side and end to end with each of the other patterns regardless of whether each pattern is in one orientation or is rotated end for end thus pattern 14a is illustrated as abutting and mating with pattern 14b in the sense that each of the constituent strip portions terminating along the left hand edge of pattern 14b aligns with and serves as a continuation of a corresponding termination on pattern 14a and the other patterns while different similarly coact the method of achieving that co action is best illustrated in fig1 and 6 of the drawings first each of the strip portions which terminates at an edge of the pattern is of a constant width such as 3 4 of an inch and that is true even though the patterns differ significantly in design from one another secondly the locations at which the strip portions 18 terminate along one vertical in the illustrated orientation edge is the same for each of the patterns and are aligned in a vertical sense with the locations at which the strips 18 terminate along the second parallel edge of the patterns to provide side to side mateability of the patterns the.
