When I applique I like to use the dark brown soft leather thimble (nimble thimble) because it is Soft and comfortable for that type of work. The sticky "dots" work well too, found mine at a LQS but they tend to sell out quick. I also have a beautiful silver thimble purchased at the Paducah Quilt Show a few years ago. Lost weight due to illness, didn't think I'd lose it in my fingers??? Anyway, a couple pieces of white adhesive tape on the inside of the thimble stopped it from slipping off.
