I read a long letter hand-written in green ink, with a dried piece of spaghetti, dated Dec 1, 1979 from Elizabeth Zimmermann.  Plus advantages of learning to knit both Continental and English/American and the answer to the question, "Does knowing the EZ method spoil you for using other patterns?"  The musical selection is a Welsh harp piece, The Ash Grove, by Cheryl Ann Fulton from her album, The Airs of Wales, in honor of Elizabeth Zimmermann's Welsh heritage.  Be sure to check out the show blog to see photos of the actual letter and the dried spaghetti.  www.knittingpipeline.blogspot.com
