This wonderful design is by Nancy Tracy and you can link to this free pattern on the Be-Stitched pattern page. It is labelled as 'Tatted Doily Row 5 Feb 2012' near the bottom of the page.
Mine is tatted in Lizbeth Size 40 threads in Violet Pink Dark (#635) and Raspberry Frappe (#157) and measures about 8 inches across.
Funny that you only notice mistakes when you are blocking the piece. I found one in the photo and I could not let it be and did correct it later. I love the negative spaces. It is rather flimsy so it has to lie flat on the table. I think I will tat this again, . . . soon.
Thank you Nancy for a lovely pattern.
