I tried several thimbles before I found the one I really like, has ring or ridge on top so needle does not slip off, to get used to it I wore it all day for several days till it just felt natural, also I wet finger before putting it on, makes it really stay in place for me. I had never used a thimble for sewing dfor many many years as just made my cloths, but when I starting quilting it became a must use!
