I took a jewelry class in high school because the ceramics class was full. My white-haired teacher, Mrs. Lewis was quite a good instructor, and trained us well in the art of jewelry making. She wouldn't let us turn in anything with "firescale" on it. Objects had to be perfectly sanded and polished to a high shine. She had this one little problem with hearts. "If you turn in anything with a heart on it, YOU FAIL THE CLASS." For my entire art career, I've had a fear of doing anything with hearts. When my students do anything with hearts, it does make me shutter a little inside. I try to stay calm.
