Make tilted squares. Tint 6 oz. fondant violet and 4 oz. teal. Use fondant roller with orange guide rings to roll out violet and teal fondant, separately, 1/8 in. thick. Use crinkled side of second smallest (1 5/16 in.) cut-out to cut 36 to 40 squares in violet fondant. Use brush and piping gel to attach randomly to cake sides, four on each side of 6 in. cake and five on each side of 8 in. cake. Use straight side of smallest (15/16 in.) cut-out to cut 36 to 40 squares in teal fondant. Use brush and piping gel to attach one square overlapping each violet square.
