I have made this doily using thread size 20, and one shuttle out of ball in first stage. In second stage I have used two shuttles. This stage was really tricky- for me- As I have made each flower with its leaves one by one, and joined that flowers with first stage. The last stage of doing it was the edge with one shuttle out of ball again. the edge was two rounds. The first one was wide, and make the doily ruffled!!! The second round makes it just nice edge as it narrowed that ruffles.It is middle size doily -about 43 cm across.
Here are its pictures (the only mistake I did when I get its final picture is ,I got it AFTER I wash it) I didn't block it well so its final picture was not good as it is in a real)
Here is the second stage of doing the flowers with their leaves.
Happy tatting for you all.
