Not trying to be QP here either but I agree with everything gaigai says. Getting the proper fit for a thimble is the first key point. I use a Thimblelady thimble - like Roxanne's has an open end so nails go through and no sweating. And I agree that the middle finger is the best so you're not on and off constantly while having to pull the needle. I also find it much more comfortable and less painful to push with the pad of the finger versus the tip. At least this keeps one of my fingers from looking like hamburger cuz my 'under' fingers certainly do!
