I was asked about books at the lecture this last Friday and so here is a list. Some of the books are out of print but you can seek them out on the net.
The book that started it all for me was THE PASSIONATE QUILTER by Michele Walker, it's a very good one. (out of print)
TRADITIONAL BRITISH QUILTS by Dorothy Osler (out of Print)
THE QUILTS OF THE BRITISH ISLES by Janet Rae (out of print)
QUILT TREASURES, The Quilters Guild Heritage Search pub. by the Quilters Guild of the British Isles (out of print)

My own book, THE WELSH QUILTING PATTERN AND DESIGN HANDBOOK is available from the Jen Jones Welsh Quilt Centre
Another book that isn't Welsh or English but will be of interest is QUILTS OF PROVENCE The Art and Craft of French Quiltmaking by Kathryn Berenson, it has also been at Edward R Hamilton Booksellers
