I got new shuttles yesterday. These are made of maple burl by Veronica from St. Petersburg, Russia. I got them from Lisa Adams at the new Tatting Corner. Only took a few days to get them in the mail. Price was really reasonable. Looks like she is going to carry some of those.
These are 2"3/4 long and about 3/4" high and 3/4" wide. The tips are really tight. I don't know if they will relax a bit with use or not. I have not tried much with them yet, but I am going to soon. They look as though they should hold a good amount of thread. I only tried them with size 10 enough to make a ring.
