Allison Chapman has been printing since she was young, taught by her Granddad in his hobby print shop. As a college student she interned with Stan Nelson in the Graphic Arts Division of the Smithsonian Institution's National Museum of American History.  She then spent over a decade teaching at the Minnesota Center for Book Arts and honing her letterpress craft. Allison inherited her Grandad's 19th century platen press and collection of vintage images, metal type, and founded Igloo Letterpress in '96 in Minnesota. She moved to Ohio in 2008 and found a home in Old Worthington, where the one press grew to 10 presses, a retail shop, print studio, bookbindery, and hub for creativity. Allison closed the retail shop in 2021 and Igloo has once again become a home based business offering custom letterpress printing and hand bookbinding.
