Grund-Variationen by Brigitte Bellon
Published 1995 by Barbara Fay. ISBN 3-925184-87-2
Hard cover, 64 pages including 25 patterns. All in German.
A fascinating selection of different sorts of ground – most Torchon, but with one Binch edging.
Contains patterns for mats, edges, insertions, collars, but the ideas for the grounds themselves are well worth the price of the book.
I bought mine from Kilparra, but although it is a fairly old book (1995) it is still available from Barbara Fay.
