Clinton, Iowa based artist Kate Callan created this lovely handbound book. Pulling colored string through each page of the book, Callan forms 3-dimensional geometric structures on each page.
Describing the project, the artist writes, “PULL contains eight explorations of hand made string formations when fully open. Some strings continue through the pages making it impossible to view more than one page at a time.”
