Decorating the Booties'n'Rattles Cake
For booties, use round tip #8 and pink frosting to pipe an elongated dot, raising up at one end to form the heel.
For rattles, use round tip #8 and blue frosting to pipe one large dot and one small dot, leaving 3/4 in. of space between. Use round tip #2 to pipe a line to connect dots.
For trim, use round tip #2 and white frosting to pipe a bow and trim on each bootie and a bow on each rattle.
