The comment was timely as I was just about to post a picture of the completed design. I will be attaching it to fabric in the centre but don't have anything appropriate at the moment so am just showing you the edging as is.
Although the picture showed 12 repeats to make a circle, I had to make 17 on mine to make it join without tension. I used DMC Babylo in size 10 and the doily is 8.5in across.
Thank you Georgia for a beautiful design.
I particularly like being able to tat a nice wide edging like that in one pass!
