This is a 22 page “Filet Crochet with Instructions” magazine style book.  It was written by Mary Fitch and published to advertise Woolco Crochet and Embroidery Cotton thread and F. W. Woolworth Stores.  It has pictures of various styles and crocheted applications followed by instructions as to how to make the items.  The book is 10 & 3/4″ by 8″ bound with staples.  It has wear at the edges but is otherwise complete and in good condition.  I am listing several additional antique crocheting books.
