Valentines as a form of American folk art were used as tokens of friendship, love, or loss in the Victorian period. Paper cut into lattice shapes of hearts and hands, were symbolic of a charitable giving heart, and sometimes associated with Shakers and other religious or social organizations. Using hair braided or woven into knots could add a personal element to the card.
