You can use any size star tip. It just depends on how big you want them to be. While you are squeezing and building your clown's body, be sure to keep the end of the tip in the icing and pull up slowly. Color striping your bag makes a really cute clown.
Every experience God gives us, every person He puts in our life, is the perfect preparation for the future that only He can see. ---Corrie Ten Boom
