One day in advance: Lightly cover top of one 12 in. separator plate with piping gel. Roll out pastel fondant 1/4 in. thick and cut sixteen 3 in. squares (4 of each color) with straight-edge wheel of Cutter/Embosser. Imprint squares, some with narrow end of tip 6, others with wavy or ridged wheels of Cutter/Embosser. As each square is imprinted, place on waxed paper, to create a 4 squares high x 4 squares wide quilt formation (cover squares with plastic wrap as you work). When quilt is complete, place a 12 in. cake circle on top, aligning at top and bottom edges. Cut around the circle and position pieces on separator plate, attaching edges with damp brush.
