Royal Society Crochet Lessons Book No. 9 contains numerous outstanding patterns. The book is dated 1917. It was published by the H.E. Verran Company. I’ve updated the antique-crochet.com site with an entire page about this book. The page features lots of photographs of the various crochet patterns in the book, plus a brief listing of patterns and contents. The rest of the book is as delightful as the cover is, so I hope you’ll check it out!
