The Pineapple Swirl Doily is my name for this doily. It comes from a book published by Ondori called Crochet Treasures. The doilies in the book did not have names. I have had the book for many, many years and treasure it. The doily was made with #30 thread, #12 hook, and measures 17 inches. Another from the WIP basket that has been completed!
