The sparkle on the snowflakes and snowmen comes from disco dust. I was really happy with the "WOW" factor that it gave the cookies! My 6 year old granddaughter thinks its the greatest stuff ever invented. A little of the stuff goes a long way and make sure you are careful with it because it is so fine that if you blow on the container accidentally it will look like a fairy exlpoded in your kitchen! The mittes I did with a traditional dusting sugar.
