I really like the Vernet Thumb Tip. The last one I had split at the seam after many years of use.
This new one was much closer to my skin color, but I had a small problem. It did not fit far enough
on my thumb to feel like it would not fall off. I tried boiling the tip until it was soft and then
letting it conform to my thumb (ouch! hot,hot,hot!) However, it did not stretch enough to feel
secure. I was afraid it would fall off with a silk in it. To fix this, I used a small amount of
tacky glue my wife uses for sewing. It made the tip feel more secure on my thumb and almost
invisible to spot. The glue was also great on my Scotch and Soda coins which were almost falling
apart.
