Knitty Gritty would rate this 'A' for 'Advanced'

Belle was in her playroom FOREVER so I finally went to check on her. She was sitting in her rocking chair in front of the mirror ... knitting. And she told me she had learned a new way to knit and announced, "Knitty Gritty would rate this A for advanced!" It looked like she was increasing with each row, somehow. She was making a triangle, basically. There was one stitch at the bottom, and she was increasing with each row, so that it was a perfect triangle.
