With my finger nails I never been able to use regular thimbles. I was using the leather thimbles until I found the leather dots and just love them. I have them stuck on my machine or in my plastic box that holds what ever project I'm working on. I also have a few on the tops of a few spools of thread. They stick to the spot on my finger I use the most and nothing gets unconformable. They are reusable many times over, one pack of 12 will last me well over a year. Also I don't have to remove them to grab anything, or get a sip of coffee.
