I use a type of finger cot but I don't think that it's the kind that they use in an office. I think I got them in the bandaid isle. They are about the thickness of balloon rubber and they fit nice and snug on your finger.
Another thing that I've used is the fat elastic that is used to hold broccoli heads together. I can't remember why I used them (menopause brain fog :roll: ) but if you have a tough needle to pull through fabric, these work really well.
