Occasionally, I shop on The Book Depository website for lace knitting books, and this one popped up today. I hadn't seen it before. It's a new release of a Niebling pattern folio, as of March 10 2015.
Publisher: Buchverlag Fuer Die Frau
Publication Date: 10 March 2015
ISBN 13: 9783897984790
Collecting Niebling patterns is somewhat of an Easter egg hunt -- it's very exciting to find one you haven't seen before.
This may have been out before, and I just never saw it, but I doubt it. I would appreciate hearing about any upcoming publications of Herbert Niebling patterns.
