Here is another teapot, this one worked with King Tut quilting thread. I wish I had measured it or put something else in the picture to give an indication of size before I gave it away. It's probably 2 1/2" wide. This thread isn't quite as forgiving as the cordonette for retro-tatting, but it is still a great thread to work with.
Tatting with tiny thread isn't as hard as you might think. (I remember my trepidation the first time I decided to try size 30 after learning how with size 10.) For these tiny threads, I need my reading glasses to count the stitches, but, heck, I need them for most "average" threads now too. Joining into a tiny space like a lock join requires a very small crochet hook, but for routine joins into picots, the hook on the Aero works fine. For making your tatting, you are working around the thread wound over your left hand, so that part is the same no matter what the thread size. It's much easier than crochet with small thread, with trying to stick the hook into each tiny stitch. If you can work with size 30, you can probably work with size 70 too, and if you can work with that, then the size 100 and quilting threads shouldn't be any problem either. Try gradually stepping down in size and see what you can do.
