Check out this fun tutorial from Chris Spooner of Spoon Graphics. (I've drawn this logo so many times, I could draw it with my left foot, standing on my head with my eyes closed!) While this tutorial might be a little "tounge-in-cheek", it also takes you through a few nifty tricks of logo/icon design.
The bright red Rolling Stones tongue and lips logo is a graphic design icon, and has been a pop culture fav for years! I don’t think you can beat it, so we’ll not create a direct copy of the original in this tut. Instead, let’s take a look at drawing our own Stones inspired tongue graphic, starting with a quick pencil sketch and finishing with a vector based graphic in Adobe Illustrator.
