Breaking this rule, however, were Anderson Peynetsa and his sister Priscilla.  At first Agnes worked with and learned from her brother Anderson, who built a body of work in the mid-1990s which established him as one of Zuni's premier potters.  Her sister Priscilla also went on to become one of Zuni's finest potters.  Many of Anderson and Agnes's older, combined effort works are signed "A. A. Peynetsa".  Early in her career, Agnes has also worked with Berdel Soseeah.

Agnes digs her own clay locally, grinds it, cleans it, and then forms the pot completely by hand.  She also grinds her own slip for the decoration and makes her own paint. However, like most Acoma and Zuni potters, she uses the electric kiln.   Defending the use of the electric kiln, the brilliant potter Noreen Simplico stated in Milford Nahohai's and Elisa Phelp's Dialogues with Zuni Potters: "Over at Indian market, when you try to enter your work, they'll downgrade it because it's fired in a kiln.  I think it's good that they have that for people who are totally traditional, but they should have room for people that, like myself, are both traditional and contemporary."
