I have seen Depression era quilts in movies that were set in the 19th century. Sticks out like a sore thumb. Some patterns were not even around then.
Saw one in an old Twilight Zone episode the other day, it is frustrating when you are trying to get a good look at it, and it is not in shot!
Once in LA, we met this lady, Margaret Cavigga.

She had a quilt store and also rented quilts to be used in movies. She said they usually damaged them and then they would wind up buying them.
