You have three choices for sprinkles: 1. jimmies - they are a long soft sprinkle that comes in rainbow colors or individual colors. These are my favorite and are what you need to put in the dough. 2. Nonpareils - these are the tiny round balls. They look festive but I prefer the jimmies if you are adding them to the batter. Nonpareils are better for decorating. 3. Sanding sugar - These come in multiple colors and are sugar crystals, use these to decorate.
