KD,
The transparent gel film sounds like a great idea. The film might offer the kind of control needed to shape the curves. I think there's a JoAnn's in the next town. But today I have to work on school stuff.
The art supply store where got the saw blade had various types of clear inks in the caligraphy section. I was afraid they wouldn't spread on the plastic properly, but you are giving me an idea that might work for hinting at the lead in the stained glass. If I can dig out my old drafting pen set that is ...
I should also note that the marker experiments were done with clear throw-away plastics like those found on placards for batteries, sushi container tops, and anything else encapsulated in clear plastic that I've bought and saved recently. So it's not the highest grade but it's plastic that I've used successfully for windows on my N scale rolling stock. The markers were Berol Prisma art colors and they were too faint. I just tried a purple Sharpie with better success. It's a bit dark but does simulate the varigated colors in the real photos I included above.
Thanks for the ideas amd interest,
Tomlinson Run Railroad
