This variation has six small rings 8-8 but the rings are kind of crowded. I suppose if I had made the picot on the first ring really big, they would have laid flatter, but this one was done a very long time ago and I've gotten smarter since. (Smarter about tatting. Stop all the snickering in the peanut gallery.)
Anyway, here's a version of the edging if you want to give it a try. The hanky edging was done in size 80. The inset which was done in 2 colours to show you where to switch shuttles was done in size 8 perle cotton.
I like this edging because:
As you can see from the diagram, it easily flows around corners.
It makes a nice wide edging, almost one inch deep in size 80 thread, in one pass.
It has enough variety that it isn't mind numbing to tat.
On the other hand, it isn't something I would attach to clothing because it would need blocking with every wash and I'd rather be tatting than blocking.
