Fondant's popularity in cake decorating isn't just because of the finished, professional look it gives. The cut-out shapes it can make are almost limitless, and they're also simple, eye-catching and easy enough for beginners to handle. It's even time-saving, since you'll need to make the shapes at least two days before you decorate the cake to allow them time to dry. You can use either ready-made or homemade fondant, and you can even mount them on wires or lollipop sticks.
Dust a clean, dry work surface with cornstarch to prevent the fondant from sticking. Dust the rolling pin with cornstarch as well, then roll out the fondant to 1/8 inch (3 mm) thick.
Dip the cookie cutter in cornstarch, then cut out star shapes from the fondant, re-dusting the cutter in cornstarch as needed to prevent sticking. Leave the stars in place until you've cut all of them out. Remove the excess fondant from around the stars, making sure all the stars still stay in place (this prevents them from being accidentally misshapen).
Move the stars with the small spatula to a cornstarch-dusted piece of waxed paper and let dry for at least 48 hours.
When the stars are dry, cut the wire into desired-length pieces with the wire cutters. Combine the 1 oz (28.3 g) of fondant with the water to make fondant adhesive, then attach one wire to the back of each star with fondant adhesive. Let dry for at least 15 minutes.
Make extra stars in case any break. An easy way to measure 1 oz (28.3 g) of fondant is to make a fondant ball that's 1.5 inches (3.8 cm) in diameter. Don't insert the wires into the cake until just before serving to prevent them from slipping out of position. This is especially true if your cake is frosted with buttercream icing. If your cake is covered with fondant, there is less chance overall of the wires shifting out of place.
Use caution when working with wire cutters.
