I feel compelled to note that you won't find a lot of negative points in the books I'm showing you. As a general rule, and especially after my last move, I don't keep books that I don't LOVE LOVE LOVE.
I love them all for different reasons, however, so that's the point of this whole thing.
Folk Shawls is available from Interweave Press and a multitude of other knitterly shopping destinations.
It includes 25 different designs, all based on different cultures, and knit in several different kinds of yarn.
It is an Interweave Book, through and through, but yarns were supplied by Schoolhouse Press, Black Water Abbey Yarns, and Baabajoes Wool Company. Baabajoes has a website, but it doesn't look entirely legitimate to me. Let me know if I am wrong, and I will link it.
The first chapter is about techniques. The rest take you through patterns inspired by the Faroe Islands, Ireland, Japan, the U. S., Iceland, Victorian England, Russia, Scotland, Mexico, South America, Norway, "Native America", the Himalayas and Spain. At the end of the book there are three more shawl patterns, listed as "variations".
There is really something here for everyone. Long, rectangular shawls, lace shawls, garter-stitch shawls, square shawls made in very which way, a cuddly cabled shawl with a pocket, and a lot more. You name it, there is a method you could try on a shawl in this book.
The Faroe shawls start from the bottom. So, they start out formidable and grow faster to make as you go.
On the other hand, if you like your knitting to start small and grow, you can work her Feather and Fan Triangle Shawl, which starts with just 7 stitches at the neck.
At the very back, there is a bibliography and a list of yarn stores. So, once again, you can delve back to sources and read Irish Earth Folk or marvel that Barbara Walker's name is mentioned in the presence of four of her books.
Wouldn't it be neat (and awfully time-consuming) to go through the backs of your books and see how often Walker is mentioned? I won't even attempt it.
