Stack cake using your preferred cake supports. Roll out 2 3" strip of white fondant one 19" long and the other 38" long. Roll to 1/4" thickness and then place Flower Fun impression mat and firmly roll over once with rolling pin. Pick up impression mat and move and repeat until both strips are entirely covered. Use a pastry wheel to cut a wavy edge on both sides of each strip. Brush a small amount of water on middle of top and bottom tier and gently press short fondant strip on top tier and the larger strip on the bottom tier.

Use a variety of all three colors. Pipe a small ball trim along top and bottom edge of strip with dark pink. Use unthined white royal icing to pipe small border at the base of each tier.
Form a couple dozen flowers using flower mold. Spray flower fun flower mold lightly with cooking spray. Use a paper towel to wipe off any excess. Push small amount of colored fondant into mold and scrape off any excess. Remove piece from mold by gently prying up edge with straight pin. Place each flower in flower former to create 3-D flower.
