I posted on these a few weeks ago, but I thought I'd highlight of few things that I experimented with when I attempted to make them again.
First of all, if you leave the macaron batter a little stiffer, they pipe into nice fluffy, puffy wooly circles. Also, the 1-1/2 inch circle template works better. They're smaller and easier to eat. I still used black licorice for the legs, but after I was done, I realized that pretzel sticks might have been better. (More people prefer to eat pretzel sticks instead of black licorice.) And instead of attaching tiny pieces of licorice for the ears, the next time I piped them on with black frosting - much easier.
