One of the tools I used to make this is a fiberglass pen. It is a great little tool, one of my favorites. But a really bad little tool if any of the fiberglass gets under your skin, which happened yesterday. I got a fiberglass splinter and it was extremely painful. It is hard to get out because you can’t see it. I searched on the Internet and discovered that duct tape is a good way to remove fiberglass splinters if the splinters are not totally embedded in the skin. It worked! Now, why should I wear gloves as recommended?
