I had a lot of thread left on the shuttle after finishing the Maranta doily.
This was tatted with that Lizbeth Size 20 Rainbow Splash Col. 184. It measures 4 inches across.
This is the first pattern in 'Tatting with Anne Orr'. But you have to tat a bunch of these to join around a fabric doily.
I could only manage one. It seems enough. The outer rings look stretched. I could not believe that the threads space was listed as 0.75 inches so I reduced it to 0.5 inches.
