So I have DS's party this Saturday and as per usual everything needs to be prepped on the day. But I was wondering, do you think I could make the Milk Arrowroot funny faces (you know the ones with icing and smarties for eyes etc) the day before or would they go soggy and soft?

Naturally I would store them in an airtight container but am just not 100% sure whether they will be alright or not? I sooooo want them to be ok so that it is one less thing for me to do on Saturday!!

Any thoughts??
