I like to use the little metal disk type stick-on thimbles because my finger doesn't feel contained and I can place it in the exact spot that works for me. The sticky dots that you put them on with wear off, but you can buy the sheets of refill sticky dots. They also have the smooth discs (called "Under Thimbles") for your bottom hand. They work the same way and your needle just slides back up through the quilt. I use both and they work great for me.
