So I ordered this royal icing mix from country kitchen:

On their website it says to just add water, but doesn't say how much water. Any ideas?

I haven't used anything like this before, but I assume you would just add water until the frosting is the right consistency. Have you ever made royal before? If not, you probably don't know what "right" looks like. For outlining, it should be pretty stiff, like stiff peaks. You have to beat the icing for 10 minutes or so. For thinner icing that you can fill in with, you'll have to add a bit more water, but you still have to beat it for 10 minutes. It is right when you drop a little frosting into the rest of it and it takes a full 10 seconds before it disappears. You can thin with water and thicken with powdered sugar or cornstarch. Just make sure you beat it, and beat it and beat it!

the fill in consistency should be like elmer's glue consistency.....not too thick, not too thin

No I have never made royal icing before, so I figured buying this would be the easiest way to use it. Thank you soo much for all the information!!!
