Create your own baby-themed cake decorations for a shower instead of purchasing them. Fondant rattles are simple enough to make for first-time fondant users. Fondant is an edible sugar paste used to cover cakes, and can be moulded into shapes. Look for coloured, prepared fondant at cake supply stores or in some craft shops.
Roll some fondant into a ball with a 2-inch diameter between the palms of your hands. The fondant has the consistency of modelling clay, but if it is hard, knead it between your hands to soften it. Keep unused fondant covered with a damp towel to keep it from drying out.
Make a 1-inch diameter ball from the fondant, rolling the fondant between your palms to smooth the ball.
Insert each of the balls into either end of a lollipop stick to make the rattle. Don't worry about letting the fondant harden just yet. You will decorate the exterior of the rattle with coloured sugar before allowing the fondant to set.
Lightly sprinkle water over each of the fondant balls on the stick.
Fill a shallow dish with the coloured sugar. Use a sugar in a contrasting colour to the rattle, or use the same colour as the fondant on the rattle to add a shine without changing the overall colour scheme. Roll the two balls in coloured sugar to add a shimmer to the fondant rattle.
Wait for 24 to 48 hours for the fondant rattle to set to a hardened state. Place the rattle on the cake or to the side as a decoration.
