The eldest daughter of Sarafina and Geronimo Tafoya, Christina was Margaret Tafoya's older sister. Like Margaret, Christina learned the traditional way to make pottery from their mother. Eventually, she became the matriarch of her own branch of the Tafoya family tradition, passing her knowledge on to her daughters Mary Cain, Mida Tafoya, Teresita Naranjo and Cecilia Naranjo, and to numerous other members of her extended family. That tradition has now been passed down to further descendants including Autumn Borts, Linda Cain, Tammy Garcia, Sharon Naranjo Garcia and Sherry Tafoya.

Known for making traditional blackware and redware, Christina coiled, scraped, polished and carved many bowls, water jars, engagement baskets, wedding vases and candlestick holders. Her favorite designs to carve seem to have been kiva steps and the avanyu (the mythic Tewa water serpent). Like her mother Sarafina and sister Margaret, Christina made many larger pieces, larger than most being produced today.

Christina enjoyed making pottery so much that she was still working almost until the day she passed on.
