Several days before decorating cake add 1/2 teaspoon Gum-Tex to 8 ounces fondant; roll out fondant 1/8 in. thick. Make 7 in. long strips for loops, and one 3 in. long strip for bow center using wavy-edge wheels of Ribbon Cutter/Embosser with 1 in. spacer. Form loops and bow center, attaching ends together with damp brush. Allow bow to dry on sides on cornstarch-dusted surface, placing crushed tissue in center of loops to support. For streamers, cut two 4 in. long strips with Ribbon Cutter/Embosser. With fingers, create a gently curved shape and let dry on cornstarch-dusted surface, supported with crushed tissue. Let dry for several hours.
