They travel across the United States in their self-constructed gypsy wagon, educating others about the book arts and teaching workshops in communities throughout the country.

At the time Peter was working as an actor at the Renaissance Pleasure Faire in Novato, California, where he hoped to participate as an artisan.

He started showing his work at the Faire in the spring of 1974, and taught visitors how to make both paper and books by hand.

[4] From 1974 to 1989 Peter and Donna Thomas made and sold books and paper at the Living History Center's Renaissance Pleasure Faire of Southern California.

It was their aim to create books in the tradition of the great private presses: limited editions, made of the finest materials and produced to the highest standards of quality.

In 1992 they printed Good Books, a bibliography of their work, listing over fifty titles representing many authors and a wide range of subjects.

They lectured and taught workshops internationally and published articles on papermaking and other aspects of the book arts.

Beginning in the 1990s, they focused their energy on documenting the history and techniques of hand papermaking as a contribution to the renaissance of the craft—through lectures, video productions about the ergonomics and techniques of traditional vat mill hand papermakers in Europe[6] and a traveling exhibition based around A Collection of Paper Samples Handmade in the USA (1993).

[5] It began with Peter attending a one-day papermaking workshop in Santa Cruz, California taught by Nida Dumsang from the Philippines.

The Good Book Press's final work was their 1987 edition of poet William Everson’s eulogy for the death of Robinson Jeffers, titled “The Poet is Dead.” The introduction of personal computers revolutionized production of fine press books.

They created a traveling artists’ book that was structurally based on a British Reading "gypsy" wagon or vardo, and functioned as a home, a physical artwork and as a metaphoric embodiment of their ideas about the changing nature of the physical book in the digital age.

He classified all physical artists' books by structure, dividing them into four distinct categories: codex, folded, single-sheet, sculptural.

In 2001 their binding of James Joyce's Ulysses was awarded the Judges Distinction for Innovation in the Helen DeGolyer Triennial for American Bookbinding.
