Really nice work, as usual, Dave...and thanks for continuing to share the details with all of us! I really like the idea of using a tea bag to simulate a cab curtain. I'm going to file that one away for future use the next time I'm trying to make a rolled-up tarp for one of my engines...will see how it turns out.
It's tough to find a suitable material that is BOTH close to scale thickness AND strong enough to hold up over time. I used a piece of a brown paper bag to make the tarp pictured below. It was the best thing I could come up with at the time, but is just a little too thick when rolled up. I think the tea bag material may fit the bill!
