Decorating the cookies varies depending on the species in question. When I do a species for the first time, it can take anywhere from 15 minutes to 45 minutes to finish a cookie. When I am doing a batch of the same cookie, I set it up so I can do three or four cookies at a time. It helps speed up the process, so on average I can decorate six to twelve cookies per hour. But there're some outside factors that work against doing any more than that. Foremost is the limitations of the human body; sore/cramping hands. And secondly is the battle against unwanted heating of the icing. All colors are made using basic white decorator icing with icing colors added until the desired color is achieved. There are about two dozen standard colors of icing color that I start with, but to get more variety (and accuracy) I will mix up a custom color. Basic cake decorating tools; icing bags with decorator tips. When I decorate the cookies, there're lots of bags and lots of tips; and I need to buy even more tips. Each little "dot" is a single squeeze of the bag of icing. When I did the ORA Clownfish cookies, I think each cookie had around 500 "dots"; that's a lot of squeezing! I'll have to re-post that old thread so you can get a better understanding of what it all involves.
