Tint all fondant light ivory. One day in advance, add 1 teaspoon Gum-Tex to 15 oz. fondant. Roll out 1/8 in. thick. Cut strips 1 in. x 6 in. for large roses and 1 in. x 4 in. for small roses. Dust Mini Muffin Pan cavities with cornstarch and position roses inside to dry. Make approximately 36 large and 40 small ribbon roses. Reserve remaining ivory fondant, tightly sealed, until ready to cover the cake.
