This pattern can be found in Emiko Kitao's Tatting Lace Corsage and Accessories book on page 46. I also tatted 3 flowers (improvised) from Pattern #52 to add to this. Done in Lizbeth Size 40 in Col. 173 Purple Marble and Col. 714 Seacrest Green.
I might try a pattern from the other book Tatting Lace Flower Accessories. I noticed that both books are also available from Handy Hands and Tatting Corner, if anyone is interested.
