I'm making about 100 snowflake cookies for my husband's work... I've already got the cookies cut and baked and in the freezer. What I'm looking to do next is to make some nice light blue royal to completely coat the tops of the cookies (i intend on pouring it over, with the cookies on a wire rack). I still want the royal to harden because I want to then decorate in white on top of the blue, and I don't want the blue to be super thick.
So... how thin can I thin my royal and still have it harden nicely?
Thanks guys!

It will take longer for the icing to harden, but you can get the icing pretty thin. Instead of pouring, you might try dipping the faces of the cookies. I have done this and it saves a bit of mess. I hold the cookie with my fingers, face down, and push it on to the icing in a wide or flat bowl. Let it drip some, then put it on a rack.

Pouring will work, also. I found that if I want to re-use the excess icing, I put it through a strainer to remove lumps and cookie crumbs.

I did this with some cookies I made for my daughter's Baptism. I thinned out the icing, placed the cookies on a wire rack and poured the icing over the cookies. I made sure to place a cookie sheet under the rack so I could still use the icing that dripped off. The icing was pretty thin and it dried just fine. I then went back and added detail with thicker icing. I am planning to make snowflake cookies too and will use the same method. Good luck.
