Great idea! We made bags of this at a cookie decorating party, and then took extra bags to kindergarten for everyone. I had so many compliments on it, and I still have parents saying to me how much easier it made their holidays as then Santa could find them when they were away from home!
What a great idea, I did this last year with my then 2 year old DD. She sprinkled it on the grass for the reindeer and it's great because it doesn't hurt the garden, in the morning all the remnants had disappeared making it look like the reindeer had been.
big hit with the christmas cookies
