Handles can make or break the look of a mug. This video by Hsin-Chuen Lin is one of the best I have seen. He not only trims the bottom of his mugs, he also trims the sides.
His handles are attached smoothly, and his tip of adding a drop of water at the base of the handle before pressing is unique.
Enjoy the video and check out his website.
