How I decorate my cookies with royal icing.....

I like the method where I first outline the cookie. I use a piping bag with a tip 3 for my outlining most of the time. When the outlining is dry I flood the cookie with the same icing with a few drops of water. Flooding will be easier. If any air bubbles comes use a pin to perforate them.

When it's dry (better if the cookies dry overnight), I pipe details on the cookie. For the second outline on the cookie I use a piping bag with a tip 2. I check if the royal icing has a good consistency - I pipe a few strings on my worktop. There are two different tipes of butterflies.....
