Funny you should say that - I have a silver thimble for TJ Lane that was suddenly not staying on my finger. Usually I can just lick my finger and it would stick on. One thing you can do is put a dab of glue on you finger to make it sticky. I was getting a bit irritated with mine not staying on so I ran my finger over the glue stick and it worked. Then I had another one got it out which was perfect, and I remembered one I use in the summer when my fingers are slightly swollen from the heat and the one in winter when my fingers are colder and thinner.
