I have seen many times where the BC frosting or other frosting is very smooth on a cake and I have heard tell about using a papertowel. How exactly is this achieved? I would like to learn how to do it for a cake I am going to make. TIA

Here's a helpful tutorial:

Thank you for sharing the links...I would never even think of looking for tips on You Tube!
