Some years ago I was able to glance over a copy of the July 1996 edition of Knots and Notes. I was struck by this pattern and jotted it down. My notes did not include the name of the motif, but it was originally from Tina Fraubergers' book "Schiffenspitze" published in Dusseldorf in 1921.
Edit: Mimi kindly notified me that Georgia Seitz has posted a scan of Tina's book at http://www.georgiaseitz.com/public/tinafrauberger/fraubergerschiffchenspitze1921.pdf. This is motif #53 on book page 54.
I have since noticed that the stitch counts are identical to the Small Cross in Mary Konior's book "Tatting with Visual Patterns", though obviously there are slight differences in the arrangement of rings and chains to make it six pointed. I have to wonder - was one inspired by the other? Or is this another case of great designers arriving at a similar look and count independently, as seems to happen so often?
I like the look of this motif with longer joining picots instead of my normal microscopic ones (it seems to benefit from the open airy look - like filigree or wrought iron) and this time I tried twisting them before joining. Some picots are bumping into the chain above; I'll fix this with pinning when I starch it.
