I sometimes need to steady my shaky right hand with my left while cutting highlights, but the piece of glass tends to move around on the light box if I am not holding it. So I bought a roll of tool chest drawer liner, which is a perforated rubbery material meant to grip whatever implements are set on it. I cut a sheet about one foot square, and cut a window in it to work over, which is about half the size of the glass piece. As long as I do not apply excessive pressure while highlighting, the glass does not budge even though I am not holding it. I don't know if this might be of help to anyone else, but I find it handy at times.
Thank you for this class!
