A method for creating decorative patterns on surfaces of cured concrete blocks includes a plurality of texturing elements secured to one or more rotatable shaft via a plurality of flexible support cables. Upon rotation of the shaft, centrifugal force causes the secured texturing elements to radially extend from the shaft. The blocks are preferably positioned such that the rotating texturing elements repeatedly come into contact with particular surfaces of the blocks, thereby forming a textured or antiqued pattern on such block surfaces. In a particular embodiment, the rotatable shaft is reciprocally moved in a direction parallel to the block surfaces to be patterned, whereby an entire block surface is exposed to the rotating texturing elements.
