After looking at the pattern a while, I decided to do this broach, or is it brooch. Hmmm, let's call it a pin. I went to my local bead store and asked for tiny pearls and bought these @ $3. a strand using 2 strands. I think it's a lovely pearl color. The thread is Altin Basak. It's from the Japanese book Tatting Lace but I couldn't find the name of the author.
It tats up in a spiral and forms 3 layers plus the center.
