This edging is from Norma Benporath was published on 8th April 1937 in The Queenslander. It is another square edging, made up of three rows.
The first two rows worked out nicely, but the third row did not turn out as I would have liked, even though I had followed the pattern without making any changes to the stitch count.
The chains in Row 3 are overlapping each other, as you can see in this close-up photo. I am not sure if blocking will straighten the chains out, but again, the overlaps could be what was intended with this design.
It is a beautiful design, but I prefer my tatting to lay as flat as possible. If I were to tat this again, I may remove one of the chains and replace one of the rings with a split ring.
