In advance: Make fondant crown. Mix 1/2 teaspoon Gum-Tex with 4 oz. fondant. Roll out 1/8 in. thick. Use pattern to cut crown; let dry on cornstarch-dusted surface. Also: Make 6 tip 131 and 18 tip 225 drop flowers with royal icing. Make extras to allow for breakage and let dry. Add tip 3 dot centers. And: Cut lollipop stick in half. Attach 3 in. pieces to back of dried crown using royal icing; leave 2 in. exposed to insert into cake.
Use tip 3 to outline and pipe-in eyes, pupils, nose, inside of ears and paw pads (smooth with finger dipped in cornstarch). Outline mouth. Cover cake with tip 16 stars. For tutu, pipe tip 127D double ruffles; add tip 8 outline waistband. Insert crown in cake. Attach flowers to crown and tutu; pipe tip 349 leaves. Pipe tip 3 number.
Drop flowers are a great way to add flowers quickly. Pipe drop flowers in buttercream directly on your cake, or pipe in royal in advance and place your flowers anywhere. Flowers will be sharper in definition when piped in royal.
One of the most popular techniques, stars come in a range of sizes and styles. Experiment with open and closed stars for variation in look. The star technique is timeless and can be used as a classic border or as a stunning fill-in for the top of a dessert.
