I think I have tried every type of thimble out there! Don't like any of them. My fingers get too hot! I tried using the little leather dots on my middle finger nail, but eventually the needle broke through and went into my fingernail. Ouch! Then I discovered those little red dots! They are called Poke-a-Dots my Jillily Studio. I take the adhesive off and super glue them to my fingernail. Stays on for weeks, keeps clean and so far has not let the needle come through.
