What is the best one to use for cake decorations? Such as small details like flower!

That depends upon your personal preference. Some folks prefer to use RI that is made with meringue powder. I prefer to use an egg-white based recipe. No special reason, I just like to work with old school techniques whenever I can, to help keep them alive.

me too! I prefer egg whites but meringue powder also works well... just a personal preference.

i like to use meringue powder... i keep a lot of it on hand, so it's easy to use in the icing... i've also heard of people using soy protein as a stabilizer.

Wow, never heard of that one. Do they use it as a substitute for egg white powder? That would be interesting, do you have more info on that? I would love to figure out a way to make some vegan royal icing.

Well I guess I left out some important info that I am a beginner and have never used RI before. So if you have any pointers or tips you would like to share please do. Oh if I plan on doing RI how long for it to dry and do I just let them air dry or what? Like I said I have never done this before, Thanks again!

Good Morning,

RI is easy to work with and very easy to make. (The biggest thing to remember in making RI is NO GREASE can touch it. Clean everything in hot, soapy water and rinse with hot water and a bit of vinegar.) You can practice on a piece of wax paper or any other flat surface that is greaseless. The are lots of instructions on the Wilton.com website.
Have lots of fun playing.

Meringue powder is dehydrated egg whites.  I have been able to make vegan royal icing, however:  http://geekycakes.com/2015/04/28/vegan-royal-icing/
