Here is a much clearer picture of the variation from Sadie's book. Not sure what the little "speckled" line through the picture is but I'm sure learning as I go. This was a fun piece to make up. Sadie's book is a lot of fun to go through and inspires lots of things.
Sadie was actually inspired by a session of tatting with Rose Mary Peel of the UK; Rose Mary certainly does inspire lots along with Mary Konior. I have several of Rose Mary's Lacet Publications as well as a number of the patterns she's published on the Internet. Mary's books are excellent too; in fact, Tatting with Visual Patterns is one of my favorite books and stays in my travel stuff, along with Jan Stawasz's book. Someday ... too many patterns/thread SIGH too little time.
