8 ounces powdered sugar
a little pinch of salt
1 egg white (or Wilton's meringue powder mixed with water: use directions on package)
1 teaspoon vanilla, almond, lemon or any other extract of your choice
food coloring of your choice
Just mix the ingredients together...you are basically making royal icing. Then you can divide your icing into portions to create your colors. Just add your food coloring in and stir! After you have all of the colors that you desire, fill individual piping bags (we used a Wiltons #3 tip). Take a baking sheet with parchment paper on it and pipe long, thin, straight lines. Repeat with each color. Make sure you allow the lines to dry for 24 hours.
When they are dry, cut them into equal pieces and you have your sprinkles!
You can use them away or store them in an airtight container!
