This is one of my favorite tricks..make a royal icing transfer and then stick it on your cookies or cupcakes. It prevents mistakes from happening, you know the ones where you waste a cookie because icing drips out in all the wrong places? Yep, those.
I start out by drawing the face shape on a piece of paper. For this set of cookies, I used 2" x 2" pieces of wax paper. I put the wax paper on top of my drawing then piped the outline and flooded it. After it dried for several hours I went back and added details to the face. The next day I flooded my cookies and peeled the Monkey face off the wax paper and gently put it on the cookie.
