Not sure if this is the right part of the forum but here goes.
I am not a scratchbuilder at the moment however I will try and make/repair parts from time to time. As such I have a variety of plastic sheet, rod, strip and brass tubes in my kit box. Today, I found something else that may be useful.
At lunch I had some prosciutto ham from the deli at my local supermarket. The meat had been very thinly sliced and pre-packed. In between each slice of meat is a sheet of what looks like plastic paper. I haven't measured it yet but it looks to be around 25x8 cm and as thin as tin foil. I don't know if it is white plastic or coated paper but it is white, very smooth, but flexible and doesn't crease unless it is sharply folded.
So thin it could be semi translucent, this could be used to skin scratchbuilt wings/fuselages etc and also would make very thin slivers for gap filling etc.
I don't have a pic but this could be a source of relatively cheap modelling material that may be easily available. Wash off any greasiness from the meat and let it dry.
Any one else using similar material?
