The First Time...
I have learned a great deal about what not to do, and that I was probably over-ambitious using the 0.5mm fabric tape, even though it was the only solution to my need for resolution.
I will qualify the tape also; I don't think it is actually fabric, but some sort of coated paper weave. It is pretty strong and is/was made by ChartPak. I don't think they manufacture it any more.
LetraSet do something similar.
Eventually though, the adhesive tape will degrade, and I do not want a wash-handbasin full of glass, so it cannot be the final resting place. Also below, shown as it appears when dark outside.
It would be nice to have something pretty to look at when I use the mirror.
Obsession is still fuel to the soul.
