Oshrit specializes in calligraphy and decoration of Judaica – Greetings, Ketubah, Mezuzah, scrolls and books. Her works are all handmade yet updated in all technological options that progress brings. She combines materials other than paper and palimpsest, such as glass and silver. Raffeld also prints on various materials such as fabric and aluminum.
Oshrit gets deep inspiration from the Jewish tradition, the accompanying aesthetics for customs and commandments, and mainly from holiday celebrations. A special collection designed by her describes twelve Mezuzot for the twelve tribes; all are displayed at the Great Synagogue of Jerusalem.
