Mirror, Mirror on the Wall - diamond-shaped doily

My first piece with pearl-tatting. The ribbon that surrounds the inner diamond-shaped motifs consists of two rounds of pearl-tatting separated a one-shuttle round. Pearl-tatting is done with 3 threads, a core thread and two working threads. I've used two shuttles and a ball. The length of this doily is 9 inch. I've used Anchor No. 60 for it.
