In Pinterest, you know when they send those mails "we found this that might be right up your alley" (and of course I like it), there's the photo of an item (already sold) in ebay, " Antique Tatted Fine Deep Wide lace wedding bridal hanky Circa 1900 NWOT" (in ebay nwot is new without tags); link is here:
I'm glad that I've found such a clear photo of the edging, probably that one is not so old. I zoomed in with the facility offered by ebay and looked at the connection points between the wheels and the inner round of rings, they are perfectly visible. In a previous post, Martha Ess kindly left a comment here, saying that she tatted it years ago and added some motifs to fill in the gaps, I loved her hint. Looking at the picture in ebay, you can see that the tatter let it almost as equal as described in the Priscilla's but the little flowers connected to the inner rings are five petals (instead of four). That could be another option. But I'm still dithering, I'm also thinking about getting rid of the inner round.
