Hernández works with a variety of media, using painting for more personal work and screen-printing for more political work. Art critic Amalia Mesa-Bains has noted:"In the 1980s, Hernandez began to develop a counterpoint to her screen printing tradition, using the medium of the pastel to create a more narrative and naturalistic rendering of characters influential within her own life. The pastel work almost serves as a pleasurable respite from the demands of a cultural critique in its joyful celebration of community." Continues Mesa Baines, "As with her artwork of her close friend and artistic madrina (godmother) Tejana singer Lydia Mendoza, she subverts, re-contextualizes, and transforms culturally traditional images into a series of feminist icons, elevating their status to that of role models." In an interview with the Mujeres Muralists, Chicana feminists art collective, her female colleagues commented about her noteworthy works: “She is best known for her depiction of Latina and Native women through her paste prints and installations.”
