I'm getting ready for today's online tatting class, so I had to finish this and empty my shuttles! It's a motif from a vintage tatting book. I don't remember which one, if you really want to know I can figure it out though no problem. Just too lazy right now.
It's worked in two rounds, the outer part first and then the inner bit to join the overlapping chains. I had to take some time with the pattern, the copy is so old some of the numbers are hard to read so I wrote it out to be easier to understand and was pretty happy with the result.
Anyway, I'm off to class!
UPDATE: the motif is from the book -LaCroix, Sophie T. Old and New Designs in Tatting, Book No. 11. and can be found by following the link on the right side of this blog to the Antique Pattern Library. Click on "catalog" and you will see it alphabetically under LaCroix.
