Using your tan buttercream pipe a slightly off center tall swirl on the cupcake, then use a Viva towel to gently smooth out the lines. You will simply lay the clean Viva paper towel over the icing then run your fingers along it and very gently press. Then I stuck a fondant bone in the point ( I cut it in half). I bought my little bone cutter at a local baking store...but if you don't have one you could shape one pretty easily or even make a bone out of melted chocolate then cooled. If you need more info on the Viva towel method check out my link here.
