I've had Roxanne thimbles for the last 10 years. It was hard to learn to use it, but once I did, I found my handquilting got a lot better. I bought the book "That Perfect Stitch" which helped me understand how she uses the thimble, plus a lot of other tips.
I also have a TJ Lane thimble, which I like just as well - I feel very elegant when I use it.
