(curled - not curved!)
That is not an original design, but a modified vintage pattern, motif n.66 in the issue n.1 of "Il lavoro chiacchierino" by Mani di Fata.
That is the photocopied page of the magazine, no more available, as far as I know.
I inserted a small curled ring in each ring of the original pattern, I'm glad of the result. I like those colours too, one thread is Lizbeth col. 154, the second is a dmc blue col. 798. Both are size 80.
The link below - if you like - points to a review by Georgia Seitz about the Italian magazine. Unfortunately I haven't an original copy of the number one, but only photocopies. If anyone has a chance to find it at their home, it would be very nice to have it scanned and donated to the Antique Patterns Library site.
