It was a book, FIMO FOLK. published by Hot Off The Press in 1992, which first brought widespread recognition to Minnesota sculptor Maureen Carlson. 

Since then Maureen has written 4 more books for Hot Off The Press, 2 for Design Originals and 5 for North Light Books.  All of Maureen's books are instructional manuals for working with polymer clay, though some of the books include stories and Maureen's personal slant on life in general.
