PS Paper is located on San Anselmo Avenue, right next to the U.S. Post Office. Since 1998, this spacious and airy shop has provided local, business and Internet shoppers with a variety of paper products, including invitations, announcements and stationery. Shop co-owner Jill Sassa's original hand-drawn illustrations can be found on many of the products. The other co-owner, Johanna Sedman, continually freshens the store's line by adding an interesting variety of new papers, materials and formats. Specialties include personalizing a charming selection of holiday cards; wedding, graduation and baby announcements; and party invitations.
