@@jasonpierce-newmodelbarmy3394 : FWIW, a lot of the model-car people I know use tissue paper (kleenex, toilet tissue, or other varieties) soaked in diluted white glue to model fabric for things like this. I've also seen lead foil used.
@@jasonpierce-newmodelbarmy3394 : Tin foil would probably work too, but actually I was thinking of lead foil -- it's a bit harder to find, but some model-supply places sell it. It tends to make much softer bends rather than the sharp "crinkly" bends that tin foil makes. When looking for a supplier, I found a company called "diodump" that sells some, and also has some pre-printed paper curtains that might be of interest.
Rather than putting a back on the building, have you considered modelling the inside? Some great opportunities for fun little details then, and rather than being just a view block then the building would become a new way to view the model; rather than glimpsing in the ajar door, you'd glimpse out of it.
Nice idea but size is the restriction here. It was an existing baseboard that I wanted to put to use, plus it needs to sit on a standard school type exhibition table when I’m showing it.
