If I have one, it’s boxed up with my seem ripper, and some bobbins. I don’t have access to that box right now. I’m thinking since I don’t remember having one specifically, then probably I don’t. I think the last time I used a thimble was in jr.high sewing class.
This Q reminds me of my husband asking me a several years ago for a darning egg (is that what it’s called?) for his socks. He didn’t know the word, but I knew what he meant. I don’t have one of those either.
